Postby Shannon Wasley 2J » Thu Mar 01, 2018 11:08 am

What are the orders of the reactants for this question?

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

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

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?

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 + ...
