A single reactant A undergoes parallel first-order reactions to give products B and C with the respective rate constants kc=1.4E-3s-1 and kb=7.0E-3 s-1. For [A]0 = 5.0E-1 M, and for zero initial product concentrations [B]0=[C]0=0.
a. Determine the [A], [B], and [C] at t=100s.
b. How can obtain the time t and the [A], [B], and [C] values at the point when the [A] = [C] in the reaction.
