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. How much time is required for 3/4th of `PH_3` to decompose?
