2. Determine the activation energy E of the reaction, for which, according to experimental data at T, K and a partial pressure of 1.01 * 105 Pa, the reaction rate constant k is known. The steric factor is taken equal to 1. The resulting activation energy and the diameter of the molecules are compared with the values given in the reference books. (Assume the diameter of atoms to be equal to the diameter of the molecule; consider the diameter of molecules based on critical or kinetic data.)
