Consider a reaction that has two parallel pathways both first-order to products. Pathway 1, leading to product B, has a rate constant of 1.34105s1. Product C- producing pathway 2 has a rate constant of 6.55104s1. 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.
Compare the functions of homogeneous and heterogeneous catalysts.
Consider a set of first-order consecutive reactions ABC. The rate constants are 8.4104s1 and 3.02105s1, respectively. Plot the concentrations of A, B, and C versus time, and determine the time necessary to produce the maximum amount of the intermediate product B.
