1)The rate constant for a certain reaction is k = 6.90×10−3 s−1 . If the initial reactant concentration was 0.950 M, what will the concentration be after 14.0 minutes?

2)A zero-order reaction has a constant rate of 3.00×10−4 M/s. If after 65.0 seconds the concentration has dropped to 8.00×10−2 M, what was the initial concentration?
