What are the correct dimensions of the equilibrium constant for the reaction ? — Chemical Equilibrium Chemistry Question
Question
What are the correct dimensions of the equilibrium constant $K_c$ for the reaction $4NH_3(g) + 5O_2(g) \rightleftharpoons 4NO(g) + 6H_2O(g)$?
Answer: B
💡 Solution & Explanation
The units of $K_c$ depend on $\Delta n_g$. Here, $\Delta n_g = (4 + 6) - (4 + 5) = 10 - 9 = 1$. Therefore, the unit of $K_c$ is $(\text{Conc})^{\Delta n_g} = (\text{Conc})^{+1}$.
