Question

If $K_{1}, K_{2} a n d K_{3}$ are equilibrium constant for formation of $A D, A D_{2} a n d A D_{3}$ respectively as follow $A + D ⇌ A D, A D + D ⇌ A D_{2}, A D_{2} + D ⇌ A D_{3}$ then equilibrium constant 'K" for $A + 3 D ⇌ A D_{3}$ is related as

K_{1} + K_{2} + K_{3} = K

Solution

The correct option is B $log K_{1} + log K_{2} + log K_{3} = log K$
$A + D ⇌ A D; K_{1} A D + D ⇌ A D_{2}; K_{2} A D_{2} + D ⇌ A D_{3}; K_{3} A + 3 D ⇌ A D_{3}; K$
As we have that $K = K_{1} . K_{2} . K_{3}$
Taking log on both sides,
$log K = log K_{1} + log K_{2} + {log}_{3}$
