### 15.15

What are the orders of the reactants for this question?

### Re: 15.15

The order of each reactant is first order. I believe this would mean that the overall reaction order is second order.

### Re: 15.15

Both of the reactants are first order because their concentrations are directly proportional to the rate increase factor.

### Re: 15.15

For clarification: If the question said that the OH- concentration doubled and the rate quadrupled, would the order with respect to OH- be second order?

### Re: 15.15

the order for both [CH3Br] and [OH-] are n=1 so the overall reaction order would be 2 because 1+1= 2

In general, rate = k * [A]^a * [B]^b ...
Thus, overall order = a + b + ...
