The decomposition of phosphine, `PH_3`, proceeds according to the following equation : `4PH_3 (g) rarr P_4 (g) + 6H_2 (g)` It is found that the reaction follows the following rate equation : Rate = `k[PH_3]`. The half-life of `PH_3` is 37.9 s at `120^@` C. What fraction of the original sample of `PH_3` remains behind after 1 minute?
