Vedclass · Answer

(B) The relationship between $K_p$ and $K_c$ is given by the equation $K_p = K_c(RT)^{\Delta n_g}$,where $\Delta n_g$ is the change in the number of moles of gaseous products and reactants.If $\Delta n_g = 0$,then $K_p = K_c$.If $\Delta n_g 
eq 0$,then $K_p 
eq K_c$.Let us calculate $\Delta n_g$ for each option:$(A)$ $2NO_{(g)} ightleftharpoons N_{2(g)} + O_{2(g)}$: $\Delta n_g = (1 + 1) - 2 = 0$.$(B)$ $2C_{(s)} + O_{2(g)} ightleftharpoons 2CO_{(g)}$: $\Delta n_g = 2 - 1 = 1 
eq 0$.$(C)$ $NO_{2(g)} + SO_{2(g)} ightleftharpoons NO_{(g)} + SO_{3(g)}$: $\Delta n_g = (1 + 1) - (1 + 1) = 0$.$(D)$ $2HI_{(g)} ightleftharpoons H_{2(g)} + I_{2(g)}$: $\Delta n_g = (1 + 1) - 2 = 0$.Since $\Delta n_g 
eq 0$ only in option $(B)$,$K_p 
eq K_c$ for this reaction.

In which one of the following equilibria,$K_p \neq K_c$?
