Question
Consider the following reaction:2 NO(g) + 2 H2(g) -> N2(g) + 2 H2O(g)
The rate law for this reaction is:
Rate = k [NO(g)]2 [H2(g)]
At a certain temperature when [NO(g)] = 0.0789 M and [H2(g)] = 0.0696 M, the rate of this reaction is 2.87e+01 M s-1. What is the reaction rate when the concentration of NO(g) is doubled, to 0.1578 M, while the concentration of H2(g) is 0.0696 M?
a) The reaction rate is 1.43e+01 M s-1.
b) The reaction rate is 1.66e+04 M s-1.
c) The reaction rate is 1.15e+02 M s-1.
d) The reaction rate is 5.75e+01 M s-1.
e) The reaction rate is 2.30e+02 M s-1.
Explanation / Answer
b) The reaction rate is 1.66e+04 M s-1.
