where C is a constant.

As an important particular case, expression (13) reduces for one

Equation (15) forms the basis of the expression of Marcelin and

Rice for the rate of decomposition of a molecule referred to in Chapter

VI. under the heading " Reaction velocity from the standpoint of the

quantum theory". The expression for the velocity constant on the

basis of statistical mechanics is given by Rice {Brit.

Ass. Report, 1915,

P- 397).
