✦ Synopsis

The kinetics of ethane oxidation was studied a t 320,340,353 and 38OoC, mixture composition 2 C ~H G + 1 02. and total pressure 609 torr. I t was found that a t 320Β°C CH20 and CH3CHO were branching agents. A series of experiments was conducted on 2C2Hfi + 0 2 oxidation in the presence of 0.7% 14C-labeled ethylene. The ethylene oxide was found to form only from C2H4, formaldehyde formed from C2H4 and C2Hs; and CH3CH0, CzHsOH, and CH30H formed only from ethane. The formation rates of C2H4, C2H40, and CH2O were calculated by the kinetic tracer method. At 320Β°C the fraction of oxygen-containing products formed from CzH4 was 16-18%, and a t 353 and 380Β°C it was 30-40%.

* Tind is the time of pressure rise by 1.5 torr.

## Abstract From transient kinetic studies of the Mg^2+^‐dependent adenosine triphosphatase of myosin subfragment 1, prepared from rabbit skeletal muscle, a seven‐step mechanism has been proposed. Features of this mechanism include two‐step processes for ATP and ADP binding in which the binary comp
