Current Question (ID: 21082)

Question:
$\text{The correct expression for the following reaction is:}$ $\text{Fe}_2\text{N(s)} + \frac{3}{2}\text{H}_2\text{(g)} \rightleftharpoons 2\text{Fe(s)} + \text{NH}_3\text{(g)}$
Options:
  • 1. $K_c = K_p(RT)$
  • 2. $K_c = K_p(RT)^{-3/2}$
  • 3. $K_c = K_p(RT)^{-1/2}$
  • 4. $K_c = K_p(RT)^{1/2}$
Solution:
$\text{Hint: Use the formula, } K_p = K_c (RT)^{\Delta n_g}$ $\text{Step 1:}$ $\text{The reaction is as follows:}$ $\text{Fe}_2\text{N(s)} + \frac{3}{2}\text{H}_2\text{(g)} \rightleftharpoons 2\text{Fe(s)} + \text{NH}_3\text{(g)}$ $\text{The relation between } K_p \text{ and } K_c \text{ are as follows:}$ $K_p = K_c (RT)^{\Delta n_g}$ $\text{Step 2:}$ $\text{Calculate the value of } \Delta n_g \text{ as follows:}$ $\Delta n_g = 1 - \frac{3}{2}$ $= -\frac{1}{2}$ $\text{The relation is as follows:}$ $K_p = K_c (RT)^{-1/2}$ $K_c = K_p(RT)^{1/2}$
