For the reaction, 2 A(g) + 2 B(g) => C(g) + 3 D(g), the following data were obtained at constant temperature.
Experiment Initial [A], mol/L Initial [B], mol/L Initial Rate, M/min
1 0.11 0.15 2.0 x 10-5
2 0.11 0.30 4.0 x 10-5
3 0.22 0.45 2.4 x 10-4
4 0.22 0.60 3.2 x 10-4
Which of the following is the correct rate law for the reaction?
1. Rate = k[A]
2. Rate = k[A]2[B]2
3. Rate = k[A][B]2
4. Rate = k[A]2[B]
5. Rate = k[A][B]
