Rate = ________

Question

The reduction of nitric oxide with hydrogen

2NO + 2H₂ ---> N₂ + 2H₂O

is second order in NO and third order overall.

Complete the rate law for this reaction in the box below.

Use the form , where '1' is understood for k[A]^m or k[B]ⁿ and concentrations taken to the zero power do not appear. Don't enter 1 for m or n.

Rate = 

Answer 1

If the reaction is 2nd order in NO and 3rd order overall, that means it must be 1st order in H₂.

Rate law: Rate = k[NO]²[H₂]
