हिन्दीIn which of the following equilibria, \( K_p \) and \( K_c \) are NOT equal?
Correct answer · Option 3
\( PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)} \)
Explanation
For the reaction \( PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)} \), \( \Delta n_g = (1 + 1) - 1 = 1 \neq 0 \). Since \( K_p = K_c(RT)^{\Delta n_g} \), here \( K_p \neq K_c \).
