1. A certain first-order reaction has a half-life of 75 minutes.
A. Find the rate constant, including the correct units.
B. How long would it take for the reaction to reach 62% completion?
2.Using the same half-life and %-completion values from #2, find the rate constant (with the correct units) and the time needed to reach 62% completion if the reaction was second-order and had a half-life of 75 minutes.
3. A certain reaction has the following form:
aA -> bB
