Phosphine, PH3, is a colorless, toxic gas that is used in the production of semiconductors as well as in the farming industry. When heated, phosphine decomposes into phosphorus and hydrogen gases. 4 PH, (g) P,(g) + 6 H, (g) This decomposition is first order with respect to phosphine, and has a half-life of 35.0 s at 953 K. Calculate the partial pressure of hydrogen gas that is present after 91.1 s if a 3.60 L vessel containing 2.14 atm of phosphine gas is heated to 953 K.

In a study of the decomposition of ammonia on a platinum surface at 856 °C NH3-1/2 N2 + 3/2 H, the concentration of NH3 was followed as a function of time. It was found that a graph of [NH3] versus time in seconds gave a straight line with a slope of -2.01×10-6 M s and a y-intercept of 6.57x103 M. Based on this plot, the reaction is order in NH3 and the rate constant for the reaction is Ms!.
