Disturbance of the Maxwellian distribution during chemical reactions in a binary mixture of monatomic gases

For the distribution function f(c, t) of the atom s of gas A, the Boltzmann gas-kinetic equation which was quoted in [2] may be written. A solution of this equation is sought in the form of an expansion off in terms of the small parameter fl (the ratio of the number of atoms reacting in 1 sec to the total number of collisions in the same period) and then in powers of the ratio mA/mB, it being assumed that fl~mA/m B. The usual Maxwellian distribution function [ mA \3/2 [ mAC2 ,
