Phosphine, ph3(g), decomposes according to the equation 4ph3(g) --> p4(g) + 6h2(g) the kinetics of the decomposition of phosphine at 950 k was followed by measuring the total pressure in the system as a function of time. the data to the right were obtained in a run where the reaction chamber contained only pure phosphine at the start of the reaction.
