CUET Chemistry Chapter-wise Question

The following questions are samples from the previous year’s CUET Chemistry paper.

Q1. An alloy of copper, silver, and gold is found to have copper constituting the ccp lattice. If silver atoms occupy the edge centers and gold is present at the body center, the alloy has a formula

1. Cu4Ag2Au
2. Cu4Ag4Au
3. Cu4Ag3Au
4. CuAgAu

Q2. Copper crystallizes in fcc with a unit cell length of 361 pm. What is the radius of the copper atom?

1. 157 pm
2. 181 pm
3. 127 pm
4. 108 pm

Q3. Alkali halides do not show Frenkel defects because

1. Cations and anions have almost equal size
2. There is a large difference in the size of cations and anions
3. Cations and anions have a low coordination number
4. Anions cannot be accommodated in voids

Q4. A solution of urea (mol. mass 56 g mol-1) boils at 100.18°C at atmospheric pressure. If Kf and Kb for water are 1.86 and 0.512 K kg mol-1, respectively, the above solution will freeze at

1. -0.654°C
2. 654°C
3. -6.54°C
4. 54°C

Q5. The solubility of a gas in liquid decreases with an increase in temperature because:

1. Dissolution of a gas in a liquid is an endothermic process
2. Dissolution of a gas in a liquid is an exothermic process
3. Gases are highly compressible
4. All of the above

Q7. Given below are the standard electrode potentials of a few half-cells. The correct order of these metals in increasing or reducing power will be

K +|K = –2.93 V, Ag+|Ag = 0.80 V,

Mg 2+|Mg = –2.37 V, Cr3+|Cr = –0.74 V.

1. K < Mg < Cr < Ag
2. Ag < Cr < Mg < K
3. Mg < K < Cr < Ag
4. Cr < Ag < Mg < K

2. 2 x 106 C
3. 8 x 105 C
4. 1 x 104 C

Q9. The pressure of H2 required to make the potential of H2-electrode zero in pure water at 298 K is

1. 10-12 atm
2. 10-10 atm
3. 10-4 atm
4. 10-14 atm

Q10. The unit of rate and rate constant are the same for a

1. zero order reaction
2. first-order reaction
3. second-order reaction
4. third order reaction

Q11. If the volume of the vessel in which the reaction 2NO + O2? 2NO2 is occurring is diminished to 1/3rd of its initial volume. The rate of the reaction will be increased by

1. 3 times
2. 6 times
3. 27 times
4. 30 times

Q12. Assertion: The solubility of any gas in any liquid is an exothermic process.

Reason: All the gas are highly soluble in any liquid.

1. Both Assertion and reason are correct, and the reason is the correct explanation of the assertion
2. Both assertion and reason are correct, but reason is not the correct explanation for assertion
3. Assertion is correct, and the reason is incorrect
4. Both assertion and reason are incorrect
