Question

____________4) When the volume of the following mixture of gases is increased, what will be the effect on the equilibrium position?4HCl(g) + O2 (g) ↔ 2H2O(g) + 2Cl2 (g)

Answer 1

Equilibrium will proceed in the left direction.

Explanations

Given the balanced chemical reaction;

`4HCl\left(g\right)+O_2(g)↔2H_2O\left(g\right)+2Cl_2(g)`

Increased volume gases results in decreased pressure. Therefore if the volume of the gas is increased, the equilibrium position will shift to the side with more moles of gas.

Since there are more moles of gases at the reactant than product, hence the reaction equilibrium will proceed in the left direction.
