Question:

The decomposition of phosphine, PH3, proceeds according to the equationPH3(g)  1/4 P4(g) + 3/2 H(g)

It is found that the reaction has the following rate equation: Rate = k[PH3]. The half-life of PH3 is 37.9 seconds at 120°C.
(a) How much time is required for three fourths of the PH3 to decompose?
(b) What fraction of the original sample of PH3 remains after 1.00 minute?
