Question

For 2 NO + O₂ → 2 NO₂,initial rate data are: The rate law is Rate = k[NO][O₂]^y:

Quizplus · Accepted Answer

The rate law has the form Rate = k[NO][O₂], which means the reaction is first order in both NO and O₂. The exponents x and y are the orders of the reaction with respect to NO and O₂, respectively. The only choice that satisfies this is B, with x = 2 and y = 1.
