A:

Consider the following reaction:

4 Zn(s) + 10 H+ + 2 NO3-  -->  4 Zn2+ + N2O(g) + 5 H2O(l)

If the rate of NO3- disappearance 8.4 x 10-4 M/s, what is the overall reaction rate?

Group of answer choices

4.2 x 10-4 M/s

4.2 x 10-3 M/s

8.4 x 10-4 M/s

1.7 x 10-3 M/s

 

B:

Consider the following reaction:

4 Zn(s) + 10 H+ + 2 NO3-  -->  4 Zn2+ + N2O(g) + 5 H2O(l)

What is the rate law for this reaction?

Group of answer choices

rate = k [H+][NO3-]

rate = k [H+]10[NO3-]2[Zn2+]4[N2O]

More information is needed to determine this.

rate = k [H+]10[NO3-]2
