Q15 / 160 · AP EAMCET 2021 (23 Aug Shift 1) · Chemistry
Identify the correct expression for the equilibrium constant of the following reaction.
$2 X(g)+Y(g) \rightleftharpoons 3 Z(g)$
- A$k=\frac{[X]^2[Y]}{[Z]^3}$
- B$k=\frac{[Z]^3}{[X]^2[Y]}$
- C$k=\frac{3[Z]}{2[X][Y]}$
- Correct answerD$k=[Z]^3[X]^2[Y]$
Solution
Given reaction is
$\begin{aligned}
& 2 X+Y \rightleftharpoons 3 Z \\
& \text {Equilibrium constant }(k)=\frac{[\text { Product }]}{[\text { Reactant }]} \\
& k=\frac{[Z]^3}{[X]^2[Y]}
\end{aligned}$
Hence, the correct answer is option: 'D'.
