### Homework Problem 15.5

Can someone please explain why you multiply by three rather than 1/3 for this problem. I thought that it would be 1/3 of the unique rate because it is 1/a rate[A]. Why do you multiply by 3 instead?

You multiply by 3 because for every reaction, 3Oxygen is required so you have to multiply the overall rate .44 by the coefficient 3
