Consider the hypothetical reaction A + B + 2C †’ 2D + 3E
In a study of this reaction, three experiments were run at the same temperature. The rate is defined as 2d[B]/dt.
Experiment 1: [A]0 = 2.0 M [B]0 = 1.0 × 10-3 M [C]0 = 1.0 M

Experiment 2: [A]0 = 1.0 × 10-2 M [B]0 = 3.0 M [C]0 = 1.0 M

Experiment 3: [A]0 = 10.0 M [B]0 = 5.0 M [C]0 = 5.0 × 10-1 M

Write the rate law for this reaction, and calculate the rate constant.
