Question

In the system, CrCl 3 (s) + H 2 O(g) + heat ⇌ CrOCl(s) + 2HCl(g), equilibrium is established. More water vapour is added to disturb the equilibrium. If the pressure of water vapour at new equilibrium is triple of that at initial equilibrium, the factor by which pressure of HCl is changed is

TestHub · Accepted Answer

Solids are excluded: K p = P HCl 2 /P H2O P HCl 2 = K p · P H2O , so P HCl ∝ √(P H2O ) Tripling P H2O multiplies P HCl by √(3) This is option (b).
