216. In the table. 19 shows the values of the rate constants at various temperatures T1 and T2. Calculate the activation energy of the reaction and determine how much of the substance has reacted by the time t, if the initial concentration of the substance is C0. The initial concentrations of the reactants are the same. The order of the reaction is calculated according to molecularity.
