Question

Consider the reaction 2NH₃(g) $\to$ N₂(g) + 3H₂(g) If the rate $\Delta$[H₂]/$\Delta$t is 0.030 mol L^-1 s^-1, then $\Delta$[NH₃]/$\Delta$t is

Quizplus · Accepted Answer

From the balanced chemical equation, we can see that the stoichiometric coefficient of NH₃ is 2, while the stoichiometric coefficient of H₂ is 3. Therefore, the rate F1F1F1S1F1F1F10[NH₃]/F1F1F1S1F1F1F10t must be negative and its magnitude should be (2/3) times the magnitude of the given rate. Rate F1F1F1S1F1F1F10[NH₃]/F1F1F1S1F1F1F10t = - (2/3) x 0.030 mol L^-1 s^-1 = -0.020 mol L^-1 s^-1. Therefore, the best choice is C.
