2 H2O (g) + 2 Cl2 (g) + heat ----------> 4 HCl (g) + O2 (g)

1. Addition of O2 means we are adding products . Addition of products increases the rate of back ward reaction . so equilibrium shift to left ie towards reactionts side. answer is a. Equilibrium will shift to the left.

2. Increasing presure favours the equilibrium towards the less number of moles side.. Reactants have less number of moles than products. equilibrium shift to left ie towards reactants side.

answer is a. Equilibrium will shift to the left.

3. Increasing size of container means increasing volume of the reaction.

increasing volume of the reaction favours towards more number of moles side. producs have more number of moles than reactants.

equilibrium shift to right side ie towards product side .

answer b. Equilibrium will shift to the right.
