Vedclass · Answer

(D) The relationship between $K_p$ and $K_c$ is given by the equation: $K_p = K_c(RT)^{\Delta n_g}$.For $K_p$ to be $NOT$ equal to $K_c$,the value of $\Delta n_g$ must be non-zero $(\Delta n_g 
eq 0)$.$\Delta n_g$ is defined as the difference between the sum of stoichiometric coefficients of gaseous products and gaseous reactants: $\Delta n_g = \sum n_p - \sum n_r$.Evaluating each option:$A$. $\Delta n_g = 2 - (1 + 1) = 0$. Thus,$K_p = K_c$.$B$. $\Delta n_g = (1 + 1) - (1 + 1) = 0$. Thus,$K_p = K_c$.$C$. $\Delta n_g = (1 + 1) - 2 = 0$. Thus,$K_p = K_c$.$D$. $\Delta n_g = (1 + 1) - 1 = 1$. Since $\Delta n_g 
eq 0$,$K_p 
eq K_c$.

In which of the following equilibria,$K_p$ and $K_c$ are $NOT$ equal?
