✦ Synopsis

A new, improved variant of the very low pressure reactor (VLPR) system with interchangeable discharge orifices was used for studying the compatibility of the chemical and physical processes occurring simultaneously. It is shown that the ratio of calculated and effective escape rate constants is a complex function of the reactor cell geometry for reactions of Eon-spherical symmetry.

The test reaction of atomic chlorine with methane proved t o be a pure chemical process free of side reactions and was used to calibrate the system. The measured rat,e constant is k , =~ 10.993 f 0.013) x 10~':' cm'/molec-s at 25°C. ' 4 new procedure is outlined for measuring the equilibrium coostant by changing the concentrations of all three components resulting in a remarkable accuracy of K , = 1.406 t 0.034 for t,he test reaction a t 25°C.
