For the mechanism [ A \xrightarrow{k_1} B \xrightarrow{k_2} C ] with (k_1 = 0.1\ \text{s}^{-1}), (k_2 = 0.05\ \text{s}^{-1}), and initial concentration ([A]_0 = 1.0\ \text{M}), ([B] 0 = [C] 0 = 0), derive expressions for ( A ), ( B ), and ( C ). Compute ([B] {\text{max}}) and the time (t {\text{max}}) at which it occurs.

[ \frac{d[A]}{dt} = -k_1[A], \quad \frac{d[B]}{dt} = k_1[A] - k_2[B], \quad \frac{d[C]}{dt} = k_2[B]. ] Chemical Kinetics And Reactions Dynamics Solutions Manual
