Q. Statement 1: The dissociation of $PC l_{5}$ decreases on increasing pressure
Statement 2: An increase in pressure favours the forward reaction.

If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1 .

Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1 .

If Statement 1 is true but Statement 2 is false.

If Statement 1 is false but Statement 2 is true.

$K_{p} = [\frac{α ^{2}}{1 - α}] [\frac{P}{1 + α}]^{1}$
An increase in pressure will decrease $α$ , to have $K_{p}$ constant and thus backward reaction occurs
