Given the following balanced equation,determine the rate of reaction with respect to [NH₃]. N₂(g)+ 3 H₂(g)→ 2 NH₃(g)

Question

Quizplus · Accepted Answer

The rate of reaction with respect to [NH₃] is the rate at which the concentration of NH₃ changes over time. From the balanced equation, we see that for every 2 moles of NH₃ produced, 1 mole of N₂ and 3 moles of H₂ are consumed. Therefore, the rate of the reaction is directly proportional to the rate of consumption of N₂ and H₂, and the rate of production of NH₃. Using the stoichiometric coefficients, we can write the rate law: Rate = - 1/3 d[H₂]/dt = -1/1 d[N₂]/dt = +1/2 d[NH₃]/dt The rate is negative for the reactants (H₂ and N₂) because their concentrations are decreasing over time, while the rate is positive for the product (NH₃) because its concentration is increasing over time. Therefore, the correct option is C, which includes a positive sign for the rate with respect to NH₃.
