The experimentally determined rate law for the reaction
2NO(g)+2H2(g)→N2(g)+2H2O(g) is rate=k[NO]2[H2].

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

#### Homework Answers

Answer #1

Part A

Total Order of the reaction = (2+1) = 3

nNO = 2

nH2 = 1

Part B

The rate law depends on the square of the concentration of NO and proportional to H2 concetration

The reaction rate will increase more if we double the concentration of NO

Hence the correct answer is Option A
