UPMSP Intermediate Chemistry Practice Questions - Uttar Pradesh UPMSP Intermediate (Class 12) Chemistry - Code 152 Exam - UPMSP Intermediate Chemistry Practice Questions - Uttar Pradesh UPMSP Intermediate (Class 12) Chemistry

Question 1

According to Raoult's law, for a solution of volatile liquids, the partial vapor pressure of each component in the solution is directly proportional to which quantity?

Its mole fraction in the liquid solution Its molarity in the liquid solution Its molality in the liquid solution Its mass percentage in the liquid solution

Correct Answer:

Its mole fraction in the liquid solution

Question 2

When 1.00 g of a non-volatile solute is dissolved in 50.0 g of benzene, the freezing point of benzene is lowered by 0.40 K. If the molal freezing point depression constant (K_f) of benzene is 5.12 K kg mol⁻¹, what is the molar mass of the solute?

128 g mol⁻¹ 256 g mol⁻¹ 64 g mol⁻¹ 512 g mol⁻¹

Correct Answer:

256 g mol⁻¹

Question 3

What is the osmotic pressure exerted by a 0.05 M aqueous solution of glucose at 300 K? (Gas constant R = 0.0821 L atm K⁻¹ mol⁻¹)

0.615 atm 2.463 atm 1.231 atm 4.926 atm

Correct Answer:

1.231 atm

Question 4

How does the Henry's law constant (K_H) of a gas in a liquid solvent change with an increase in temperature, and what is its effect on gas solubility?

K_H decreases with increasing temperature, and gas solubility increases K_H remains unchanged, and gas solubility is independent of temperature K_H decreases with increasing temperature, and gas solubility decreases K_H increases with increasing temperature, and gas solubility decreases

Correct Answer:

K_H increases with increasing temperature, and gas solubility decreases

Question 5

A mixture of nitric acid (68%) and water (32%) forms a maximum boiling azeotrope at 393.5 K. What type of deviation from Raoult's law does this solution exhibit?

Negative deviation from Raoult's law because A-B interactions are stronger than A-A and B-B interactions Positive deviation from Raoult's law because A-B interactions are weaker than A-A and B-B interactions Zero deviation because it behaves as an ideal solution at the azeotropic composition Positive deviation because the total vapor pressure of the solution is maximum

Correct Answer:

Negative deviation from Raoult's law because A-B interactions are stronger than A-A and B-B interactions
