Consider the first order reaction: A → products studied at 277 K. If the rate constant, k, is found to be 0.571 1/s, and the Arrhenius factor, A, is 1.649, what is the activation energy for the reaction?
Part A: The rate constant for a certain reaction is k = 1.90×10−3 s−1 . If the initial reactant concentration was 0.150 M, what will the concentration be after 7.00 minutes? Part B: A zero-order reaction has a constant rate of 4.60×10−4 M/s. If after 30.0 seconds the concentration has dropped to 8.00×10−2 M, what was the initial concentration? Part C: A certain reaction has an activation energy of 60.0 kJ/mol and a frequency factor of A1 = 7.80×1012 M−1s−1...
