A proposed mechanism is:
1) 2 A + B – C (slow)
2) C → A + D (fast)
If this mechanism is correct, by what numerical factor should the rate of reaction
increase if [A] is increased by a factor of (4.44x10^0)?
Hint: First determine the rate law predicted by this mechanism and then set up a
ratio of the two runs.
Enter your answer in scientific notation with 3 sig figs. Do not include any units in
your answer.
Do not round any intermediate calculations.
Note: Your answer is assumed to be reduced to the highest power possible.
