QuestionType:

MCQ

Question:

Which of the following is not the characteristic of physisorption?


A:

It arises because of van der Waals forces.

B:

It is not specific in nature

C:

Enthalapy of adsorption is high

D:

It results into multi molecular layers on adsorbent surface under high pressure

Correct Answer

Enthalpy of adsorption is high.

Explanation

Physisorption, or physical adsorption, occurs due to weak Van der Waals forces and is not specific to any particular substance. The enthalpy of adsorption in physisorption is generally low (not high) because the forces involved are weak compared to chemisorption. Additionally, physisorption can result in multilayer adsorption on the adsorbent surface, especially under high pressure. Therefore, the statement about high enthalpy of adsorption is incorrect for physisorption.

A:

$390.5 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

B:

$643.3 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

C:

$461.3 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

D:

$208.5 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

Correct Answer

390.5 S cm² mol⁻¹.

Explanation

Given values:

- $\Lambda_m^{\circ}(\mathrm{NaCl})=126.4 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

- $\Lambda_m^{\circ}(\mathrm{HCl})=425.9 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

- $\Lambda_m^{\circ}(\mathrm{NaOAc})=91.0 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

Now, calculate $\Lambda_m^{\circ}(\mathrm{HOAc})$ :

$\Lambda_m^{\circ}(\mathrm{HOAc})=91.0+425.9-126.4$

$\Lambda_m^{\circ}(\mathrm{HOAc})=390.5 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$

Question Type:

MCQ

Question:

The products formed at cathode and anode by electrolysis of aqueous NaCl solution respectively are

A:

$\mathrm{Na}, \mathrm{Cl}_2$

B:

$\mathrm{Na}, \mathrm{O}_2$

C:

$\mathrm{H}_2, \mathrm{Cl}_2$

D:

$\mathrm{H}_2, \mathrm{O}_2$

Correct Answer

$\mathrm{H}_2, \mathrm{Cl}_2$

Explanation

Explanation: During the electrolysis of aqueous NaCl solution, the products formed at the cathode and anode are:

- At the cathode (reduction): The reduction reaction involves the formation of hydrogen gas $\left(\mathrm{H}_2\right)$ because water is reduced more easily than sodium ions.

$2 \mathrm{H}_2 \mathrm{O}+2 e^{-} \rightarrow \mathrm{H}_2+2 \mathrm{OH}^{-}$

- At the anode (oxidation): Chloride ions $\left(\mathrm{Cl}^{-}\right)$are oxidized to form chlorine gas $\left(\mathrm{Cl}_2\right)$.

$2 C l^{-} \rightarrow C l_2+2 e^{-}$

Thus, the products formed at the cathode and anode are hydrogen gas $\left(\mathrm{H}_2\right)$ and chlorine gas $\left(\mathrm{Cl}_2\right)$, respectively.

MCQ

Question:

Calculate the molarity of a solution containing 5 g of NaOH in 450 mL solution

A:

$0.278 \times 10^{-3} \mathrm{M}$

B:

$0 \cdot 278 \mathrm{M}$

C:

$2.78 \times 10^{-3} \mathrm{M}$

D:

$2.78 \mathrm{M}$

Correct Answer

0.278 M.

Explanation

Given:

- Mass of $\mathrm{NaOH}=5 \mathrm{~g}$

- Volume of solution $=450 \mathrm{~mL}=0.450 \mathrm{~L}$ (since $1 \mathrm{~L}=1000 \mathrm{~mL}$ )

Step 1: Calculate moles of NaOH

The molar mass of NaOH is:

$\text { Molar mass of } \mathrm{NaOH}=23+16+1=40 \mathrm{~g} / \mathrm{mol}$

Now, calculate the moles of NaOH :

$\text { moles of } \mathrm{NaOH}=\frac{\text { mass }}{\text { molar mass }}=\frac{5 \mathrm{~g}}{40 \mathrm{~g} / \mathrm{mol}}=0.125 \mathrm{~mol}$

Step 2: Calculate the molarity

Now, use the molarity formula:

$M=\frac{0.125 \mathrm{~mol}}{0.450 \mathrm{~L}}=0.278 \mathrm{M}$

QuestionType:

MCQ

Question:

Atoms of element B form a hep lattice and those of element A occupy $2 / 3 \mathrm{rd}$ of tetrahedral voids. What is the formula of the compound formed by the elements $A$ and B?

A:

$\mathrm{A}_3 \mathrm{~B}_4$

B:

$\mathrm{A}_4 \mathrm{~B}_3$

C:

$\mathrm{A}_2 \mathrm{~B}_3$

D:

$\mathrm{A}_3 \mathrm{~B}_2$

Correct Answer

$\mathrm{A}_3 \mathrm{~B}_2$

Explanation

Step 1: Number of atoms in one unit cell of B (hcp structure)

In an hcp lattice, the number of atoms per unit cell is 6.

Step 2: Number of tetrahedral voids in one unit cell of B

In the hcp structure, there are 8 tetrahedral voids per unit cell.

Step 3: Number of voids occupied by A

Since A occupies $2 / 3$ of the tetrahedral voids, the number of voids occupied by $A$ in the unit cell of $B$ is:

$\text { Number of voids occupied by } A=\frac{2}{3} \times 8=\frac{16}{3} \approx 5.33$

Thus, the number of atoms of A that occupy the voids is 5.33 per unit cell.

Step 4: Determine the ratio of A to B

From the above, we know that there are 6 atoms of $B$ and 5.33 atoms of $A$ in one unit cell.

The simplest ratio of A to B is approximately 3:2 (since 5.33 atoms of A corresponds to 3 atoms when rounded).

Thus, the formula of the compound is: A3B2

Questions related to CUET UG

Have a question related to CUET UG ?

Hello,

You cannot get admission to engineering courses in Delhi University (DU) through CUET scores .

DU offers engineering courses under its Faculty of Technology, and admissions to these courses are based on JEE Main scores, not CUET.

Hope it helps !

Hello,

Delhi University (DU) offers various engineering courses under its Department of Technology.

Admission to these courses is primarily based on the Joint Entrance Examination (JEE) Main scores. However, some courses may also consider CUET (Common University Entrance Test) scores for admission.

The exact number of seats filled through CUET scores can vary each year and are not publicly disclosed.

Hope it helps !

Admissions for CUET aren't solely based on 2 Non-Med Percentage along with JEE Mains percentile. The eligibility criteria for CUET require students to have scored at least 50% marks in their Class 12th exam for general candidates and 45% for reserved categories.


Additionally, CUET has its own exam pattern, which includes multiple-choice questions divided into three sections:

- Section 1: Language proficiency(English/Hindi/regional languages)

- Section 2: Domain-specific subjects

- Section 3: General Aptitude


It's also important to note that while JEE Mains is a separate entrance exam, some universities may consider both CUET and JEE Mains scores for admission to certain programs. However, the specific admission criteria may vary depending on the university and course.


To confirm the admission criteria for your desired course, I recommend checking the official websites of the participating universities or contacting them directly.

Yes, if the CUET UG application form does not ask for the 10th marksheet upload and only requires a photograph and signature, your application should still be considered valid. Since you are currently appearing for the 12th exams, the system may not require additional documents at this stage. However, double-check the official guidelines or contact CUET support to confirm.

A PG (Postgraduate) degree in Forensic Science, specifically an M.Sc. in Forensic Science, is a two-year program that provides specialized knowledge and skills in the scientific analysis and application of techniques for collecting and analyzing evidence to solve crimes.
