ON the basis of the kinetic theory, molecules in a liquid, at a given temperature, are at a certain energy level. Before the molecules can undergo a transition to a higher energy level they must acquire an activation energy designated by E. The Maxwell distribution law states that the number of molecules possessing sufficient energy for transition are in relation to the expression e‐E/RT where R is the gas particularly over extended temperature ranges, a study has been made of these deviations to ascertain whether they are anomalous or whether equation la fails to apply to such cases.
