[NO] [H2] initial rate
0.006 0.003 0.075
0.001 0.009 0.018
1) Find the order of the reaction relative to hydrogen gas H2.
2) Find the order of the reaction relative to nitrogen monoxide NO.
Caan anyone explain what should I do here? I can solve it normally but what is relative to H2 and No?

It's just determining the order of reaction with respect to the hydrogen gas and nitrogen monoxide. State whether it is of zero, first, second order.... The overall order of reaction would be the sum of both orders.

The order of the reaction relative to H2 is the way the concentration of H2 ONLY affects the rate. So, if you had a very large excess of NO, then the NO concentration won't affect the rate- it will be limited only by the H2 concentration.
If the rate is directly proportional to the H2 concentration, the the reaction is first order with respect to H2. If the rate is directly proportional to NO concentration, the rate is first order with respect to NO.
Without doing the maths on this, I imagine it's second order overall, yes? In that case, it's first order with respect to NO, first order with respect to H2, and second order overall.
