Given the rate law rate=k[H2][NO]^2 and the value of k at 1000K is 38 M^-1 s^-1, find the rate when [H2]=0.006M and [NO]=0.004M

Question

Answer choices:

8.10E-5 M/s

5.21E-4 M/s

1.88E-8 M/s

3.65E-6 M/s

None of the above

Answer 1

This question is a straight forward "plug and chug".

Use the equation given:

rate = k[H₂][NO]²

rate = 38 M^-1s^-1 (0.006M) (0.004M)²

rate = 3.65x10^-6 M/s
