$H_2(g) + I_2(g) \rightleftharpoons 2HI(g)$

(A) According to Le Chatelier's principle,a change in pressure affects the equilibrium position of reactions where there is a change in the number of moles of gaseous species,i.e.,$\Delta n_g \neq 0$.For option $A$: $H_2(g) + I_2(g) \rightleftharpoons 2HI(g)$,$\Delta n_g = 2 - (1 + 1) = 0$.Since $\Delta n_g = 0$,the equilibrium position is not affected by a change in pressure.

At equilibrium,what happens to the boiling point of $H_2O$ when pressure is increased?

Easy

View Solution

The equilibrium constant for a reaction $A + B \rightleftharpoons C + D$ is $1 \times 10^{-3}$ at $298 \ K$ and is $2$ at $273 \ K$. The chemical reaction resulting in the formation of $C$ and $D$ is
