1) This document describes a consecutive first-order reaction where species A reacts to form species B, which then reacts to form species C. The rate equations for each step are provided. 2) If the initial concentrations of A, B, and C are 1, 0, and 0, respectively, the expressions for [A], [B], and [C] as a function of time can be derived. 3) The document requests plotting [A], [B], and [C] over time for the case where k1 = 1 and k2 = 0.1.
