The reaction of NO gas with H2 gas has the following rate law: Rate = k[H2][NO]2

A proposed mechanism is:

Step 1: H2 (g) + 2 NO (g) → N2O (g) + H2O (g)

Step 2: N2O (g) + H2 (g) → N2 (g) + H2O (g)

What is the molecularity is step 1?

What is the molecularity in step 2?

Which step is the rate-determining step?
