41. Solution to Chemistry Problem
20. Table 16 shows the values of the rate constants k1 and k2 for the reaction at two different temperatures T1 and T2. Calculate the activation energy of this reaction, find the rate constant at temperature T3, and determine how much of the substance has reacted by time t if the initial concentrations of the substances are the same). Determine the temperature coefficient of the reaction rate and check the applicability of the Van´t Hoff rule using an example. Calculate the reaction order by molecularity.
Reaction T1, K k1 T2, K k2 1 T3, K Time, min C0, mol/l
CH3COOCH3 H2O→CH3COOH CH3OH 298.2 0.653*10-3 308.0 1.163*10-3 313.2 313.2 1.60
