Question
At $27^\circ\text{C}$, the equilibrium constant $K_c$ for the reaction $2A(g) + B(g) \rightleftharpoons 4C(g)$ is $3 \times 10^{-5}$. What is the value of $K_p$ in terms of the universal gas constant $R$?
Answer: A
💡 Solution & Explanation
First, calculate $\Delta n_g = 4 - (2 + 1) = 1$. The absolute temperature $T = 27 + 273 = 300\text{ K}$. Using $K_p = K_c(RT)^{\Delta n_g}$, we get $K_p = 3 \times 10^{-5} \times (R \times 300)^1 = 900 \times 10^{-5} R = 9 \times 10^{-3} R$.
