For the non-stoichiometric reaction , the following kinetic data were obtained in three separate experiments, all at 298 K.

| Initial concentration (A) | Initial concentration (B) | Initial rate of formation of C (mol L s) | |---|---|---| | 0.2 M | 0.2 M | 0.12 | | 0.2 M | 0.4 M | 0.24 | | 0.4 M | 0.2 M | 0.24 |

The order of the reaction is .

Answer: 2

Solution

Comparing rows 1 and 2 ( fixed, doubled): rate doubles, so order in is 1. Comparing
