Problem 127b
Textbook Question
Textbook QuestionConsider the reversible, first-order interconversion of two molecules A and B: A kfkrB where kf = 3.0 * 10-3 s-1 is the rate constant for the forward reaction and kr = 1.0 * 10-3 s-1 is the rate constant for the reverse reaction. We'll see in Chapter 15 that a reaction does not go to completion but instead reaches a state of equilibrium with comparable concentrations of reactants and products if the rate constants kf and kr have comparable values. (c) What are the relative concentrations of B and A when the rates of the forward and reverse reactions become equal?
