a. Overall third order, A to the first, B to the second
b.
c.
Explanation:
When A is tripled in trial 3 from trial 1, and B is kept constant the rate also triples, so A is to the first order.
When A is kept constant from trial 3 to trial 2 but B is doubled, the rate quadruples, therefore B is to the second order.
