Cordova · Answer 1

rate = l[A][B]

Explanation:

We are given the information that step 1: A + B → 2C + D is the the rate determinng steps, while the other 2 are fast in the reaction mechanism.

The rate law which is what we need to determine in this question is dependent on the the slowest step,

Therefore, the rate law will be a second order overall and dependent on the concentrations of A and B:

rate = k [A][B]
