For the general reaction 2A + B $\rightarrow$ products, the rate equation takes the following form: rate of reaction = k[A]²[B]¹. What are the units of the rate constant, k?

Question

Quizplus · Accepted Answer

To determine the units of the rate constant, we can examine the equation for rate: rate of reaction = k[A]²[B]¹. The units of rate are typically given as mol dm-3 s-1, which means that the units of k must cancel out the units of [A] and [B] to leave mol dm-3 s-1. We can see that: k = rate of reaction /[A]²[B]¹ = (mol dm-3 s-1) / (mol dm-3)²(mol dm-3)¹ = mol⁶ dm³ / mol^-2 s^-1. Therefore, the correct answer is (D).
