S The rate constant for a certain reaction is k = 1.30*10-3s. If the initial reactant concentration was 0.100 M, what will the concentration be after 11.0 minutes? Express your answer with the appropriate units. Part B A zero-order reaction has a constant rate of 4.80*10-4 M/s. If after 40.0 seconds the concentration has dropped to 5.50 10-2 M, what was the initial concentration? Express your answer with the appropriate units
