Kinetics Review

Consider the following rate law: Rate = k[A]ⁿ[B]^m
How are the exponents n and m determined?

• by using balanced chemical equation
• By using the subscripts for the formulas
• By educated guess
• By experiment

step 1: O3 -> O₂ + O
step 2: O₃ + O -> 2 O₂
The oxygen atom (O) is considered to be a(n)...

What is a catalyst?

• Something added to a reaction to slow it down
• Something added to a reaction to speed it up
• Something added to a reaction just for fun
• Something added to a reaction to change its concentration

What would be my the overall order of this rate law? 
Rate=[A]²[B]¹

• 0 Order
• 1st Order
• 2nd Order
• 3rd Order
