Identify the correct expression for the equilibrium constant of the following reaction. $2 X(g)+Y(g) \rightleftharpoons 3 Z(g)$
  1. $k=\frac{[X]^2[Y]}{[Z]^3}$
  2. $k=\frac{[Z]^3}{[X]^2[Y]}$
  3. $k=\frac{3[Z]}{2[X][Y]}$
  4. $k=[Z]^3[X]^2[Y]$

Solution

Given reaction is $\begin{aligned} & 2 X+Y \rightleftharpoons 3 Z \\ & \text {Equilibrium constant }(k)=\frac{[\text { Product }]}{[\text { Reactant }]} \\ & k=\frac{[Z]^3}{[X]^2[Y]} \end{aligned}$
