Consider the reaction X_2 Y(g) ⇌ X_2(g)+1/2 Y_2(g) The equation representing correct relationship between the degree of dissociation ( x ) of X_2 Y (…
Consider the reaction
$$X_2 Y(g) \rightleftharpoons X_2(g)+\frac{1}{2} Y_2(g)
$$
The equation representing correct relationship between the degree of dissociation ( $\displaystyle x$ ) of $\displaystyle \mathrm{X}_2 \mathrm{Y}(\mathrm{g})$ with its equilibrium constant Kp is $\displaystyle \_\_\_\_$.
Assume $\displaystyle x$ to be very very small.
Official answer
From NTA’s final answer key for this paper.
