Q. The value of $K_{p}$ for the following reaction $2H_{2}S(g) \rightleftharpoons 2H_{2}(g) + S_{2}(g)$, is $1.2 \times 10^{- 2}$ at $106.5℃$. The value of $K_{c}$ for this reaction is
A) $= 1.2 \times 10^{- 2}$
B) $< 1.2 \times 10^{- 2}$
C) $> 1.2 \times 10^{- 2}$
D) None of these
Explanation
(b)
$K_{p} = K_{c}(RT)^{\mathrm{\Delta}n_{g}}$
Here, $\mathrm{\Delta}ng = 1$
Thus, $K_{c}$ will be less than $K_{p}$
