Question
Consider the fundamental equilibrium $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$ with a known equilibrium constant $K_1$. Which of the following relationships is/are correct for the given modified forms of this reaction?
💡 Solution & Explanation
When a reaction is reversed, the new equilibrium constant is the inverse ($1/K$). When multiplied by a factor $n$, the new constant is raised to the power $n$ ($K^n$). For option A, the reaction is reversed and multiplied by $1/2$, so $K_2 = (1/K_1)^{1/2} = (K_1)^{-1/2}$. For option B, the reaction is multiplied by $2$, so $K_3 = (K_1)^2$. Options C and D misapply these rules.
