What is the rate determining step?

Answer 1

slowest step, and it has the largest activation energy

Question 2

the rate law of the rate determining step determines…

Answer 2

the rate law of the overall reaction

reaction intermediate

Answer 3

species produced in one step and reacted in another step; they cancel
