Using the equation:

Question

Quizplus · Accepted Answer

According to the equation provided, the equilibrium constant (K_a) is equal to the ratio of the forward rate constant (K_w) and the reverse rate constant (K_b). Therefore, the correct choice is B, which rearranges the equation accordingly. Choices A, C, and D have incorrect rearrangements of the equation.
