Q1. Which of the following is the correct expression for the equation of state of van der Waals gas?
Answer : Option C
Explaination / Solution:
No Explaination.


Q2. The equilibrium constant for a reaction at room temperature is K1 and that at 700 K is K2. If K1 > K2, then
Answer : Option A
Explaination / Solution:

T1 = 25 + 273 = 298 K

T2 = 700 K


ΔHº is –ve ie., forward reaction is exothermic



Q3. In an adiabatic process, which of the following is true ?
Answer : Option B
Explaination / Solution:
No Explaination.


Q4.

Stomach acid, a dilute solution of HCl can be neutralised by reaction with Aluminium hydroxide

Al (OH)3 + 3HCl (aq) → AlCl3 + 3 H2O

How many millilitres of 0.1 M Al(OH)3 solution are needed to neutralise 21 mL of 0.1 M HCl ?

Answer : Option B
Explaination / Solution:

M1 × V1 = M2 × V2                [ 0.1 M

Al(OH)3 gives 3 × 0.1 = 0.3 M OH– ions]

0.3 × V1 = 0.1 × 21

V1 = 01x21 / 0.3 = 7ml
