Part A
The rate constant for a certain reaction is k = 3.30Ã10â3 sâ1 . If the initial reactant concentration was 0.750 M, what will the concentration be after 2.00 minutes?
**The answer is NOT 5.04 M**
Part B
A zero-order reaction has a constant rate of 2.20Ã10â4M/s. If after 35.0 seconds the concentration has dropped to 6.00Ã10â2M, what was the initial concentration?
Express your answer with the appropriate units.
**The answer is NOT 0.067 M**
