Part A: The rate constant for a certain reaction is k = 2.30×10−3 s−1 . If the initial reactant concentration was 0.450 M, what will the concentration be after 3.00 minutes?

Part B: A zero-order reaction has a constant rate of 4.10×10−4 M/s. If after 35.0 seconds the concentration has dropped to 5.50×10−2 M, what was the initial concentration? Express your answer with the appropriate units.
