The experimentally determined rate law for the reaction 2NO( g )+2H2( g )N2( g )

Question

The experimentally determined rate law for the reaction
2NO(g)+2H2(g)N2(g)+2H2O(g)

is rate = k[NO]2[H2].

Part A

What are the reaction orders in this rate law?

Part B

Would the reaction rate increase more if we double the concentration of NO or the concentration of H2?

A. The reaction rate will increase more if we double the concentration of H2. B. The reaction rate will increase more if we double the concentration of NO. C. The effect of doubling the concentration of NO will be the same as the effect of doubling the concentration of H2.

Explanation / Answer

2NO(g)+2H2(g)N2(g)+2H2O(g)

is rate = k[NO]2[H2]

part A

order w.r.t NO = 1

H2 = 1

PART B

C. The effect of doubling the concentration of NO will be the same as the effect of doubling the concentration of H2.
