Direction (Q. Nos. 1-8) This section contains 8 multiple choice questions. Each question has four
choices (a), (b), (c) and (d), out of which ONLY ONE option is correct.

Q. The equilibrium which is not affected by volume change at constant temperature is

The binding of oxygen by haemoglobin (Hb) forming (HbO₂), is partially regulated by the concentration of H₃O + and dissolved CO₂ in blood.

Release of O₂ is favoured when there is

Aerated water contains CO₂ dissolved in water

CO₂(g) + H₂O(l) H₂CO₃(aq)

Variation of solubility (s) with pressure (p) is shown by 

Variation of log K_p with temperature. 1/T is given by for the equilibrium.

Q. What is per cent dissociation if 1 M AB is dissociated in the presence of 1 M A⁺? 

When hydrochloric acid is added to cobalt (II) nitrate solution at room temperature, the following reaction takes place

Q. The solution is blue at room temperature. However, it turns pink when cooled in a freezing mixture. Based upon this information, which of the following expression is correct for the forward reaction?

Consider the following equilibrium in a closed container
