44. Solution to Chemistry Problem

5. Table 3 shows the kinetic parameters of the reactions:
Ea is the activation energy, A is the pre-exponential factor in the Arrhenius equation, and n is the reaction order. Determine the reaction rate constant at a given temperature T1 and the amount of starting materials (C) consumed over time (t) if the initial concentrations of the starting materials are equal (C0).
