[905084274]

For a reaction 2A + B 2C, with the rate equation: Rate = k[A]2[B]
(a) the order with respect to A is 1 and the order overall is 1.
(b) the order with respect to A is 2 and the order overall is 2.
(c) the order with respect to A is 2 and the order overall is 3.
(d) the order with respect to B is 2 and the order overall is 2.
(e) the order with respect to B is 2 and the order overall is 3.

what is the answer to this one? I found it online and am also confused

The overall order is 2+1 = 3.
The order with respect to A is 2, and the order with respect to B is 1.

This makes (C) the answer
