Part A) The rate constant for a certain reaction is k = 8.80×10−3 s−1. If the initial reactant concentration was 0.550 M, what will the concentration be after 18.0 minutes? Express your answer with the appropriate units. Part B) A zero-order reaction has a constant rate of 3.80×10−4 M/s. If after 45.0 seconds the concentration has dropped to 4.50×10−2 M, what was the initial concentration? Express your answer with the appropriate units.
