## multiple choice rate

$\frac{d[R]}{dt}=-k[R]^{2}; \frac{1}{[R]}=kt + \frac{1}{[R]_{0}}; t_{\frac{1}{2}}=\frac{1}{k[R]_{0}}$

### multiple choice rate

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

### Re: multiple choice rate

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