Initial[A] Initial [B] Initial Rate, M/s

.740 M .010 M 3.00e-10
.740 M .030 M 8.09e-9
.740 M .060 M 6.46e-8
.740 M .070 M 1.03e-7

What is the order of the reaction with respect to the concentration of B?

1 answer

3rd order

the ratio of initial rates is the cube of the ratio of initial concentrations
