Compounds A and B react to produce compounds C and D according to the following equation.
A + B → C + D
The following data were collected from several runs of the reaction carried out at 65°C.
Run # [A]initial(mol/L) [B]initial (mol/L) Initial rate (mol/L·min)
1 0.35 0.35 5.0 ✕ 10⁻⁴
2 0.70 0.35 1.0 ✕ 10⁻³
3 0.70 0.70 2.0 ✕ 10⁻³
4 0.35 0.70 1.0 ✕ 10⁻³
In the table, the initial concentrations of A and B used to start the reaction are shown along with the initial rate of reaction measured at the start of each run. Use these data to determine the rate law for the reaction. (Rate expressions take the general form: rate = k . [A]a . [B]b. Do not solve for k.
