But because this is an elementary reaction and the coefficient is two, what that means is we'll have a coefficient of two on top of that A. So this reaction is second order with respect to K and with respect to A. And the overall order is also second order. So this reaction and this reaction, they are both second order. The only difference is we have a single reactant here but we have two reactants here. In this particular case if we double A, then we quadruple the velocity because two to the power of two gives us four.
