Question

Match the column. The codes for the lists have choices $\left(A\right),\left(B\right),\left(C\right)and\left(D\right)$ out of which only ONE is correct.

Answer 1

(A) For the reaction $N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$ increase in pressure accelerate the forward reaction.

(B) For the reaction $2NO\left(g\right)\rightleftharpoons N_2\left(g\right)+O_2\left(g\right)$ at constant volume introduction of inert gas, has no effect.

(C) For the reaction $CaC{O}_3\left(s\right)\rightleftharpoons CaO\left(s\right)+C{O}_2\left(g\right)$ $K_p=P_{total}$
Le-chateliers principle is applicable and for $P_{total}=P_{CO2}$, which is equal to Kp for the given reaction.

(D) For the reaction $PC{l}_5\left(g\right)\rightleftharpoons PC{l}_3\left(g\right)+C{l}_2\left(g\right)$ increase in volume favors forward reaction.
