Chapter 20, Problem 20.100E

Consider a reaction that has two parallel pathways (both first-order) to products. Pathway $1$, leading to product B, has a rate constant of $1.34\times {10}^{-5}{\text{s}}^{-1}$. Product C- producing pathway $2$ has a rate constant of $6.55\times {10}^{-4}{\text{s}}^{-1}$. Plot the concentrations of A, B, and C versus time, and determine the time necessary to produce the maximum amount of the kinetically favored product.
