(A)After experimentation you have determined the following rate equations:

Question

1. Rate = k[H2] [NO]2
2. Rate = k[H2]2[O2]
3. Rate = k[H2] [NO]
Identify the order of reaction for each of these rate equations

Answer 1

1. The order of reaction for equation 1 is 1st order with respect to [H2] and 2nd order with respect to [NO]. The overall order of reaction is 3rd order.

2. The order of reaction for equation 2 is 2nd order with respect to [H2] and 1st order with respect to [O2]. The overall order of reaction is 3rd order.

3. The order of reaction for equation 3 is 1st order with respect to [H2] and 1st order with respect to [NO]. The overall order of reaction is 2nd order.
