The gas phase decomposition of phosphine at 120 °C PH3(g) →→→1/4 P4(g) + 3/2 H₂(g) is first order in PH3. During one experiment it was found that when the initial concentration of PH3 was 0.0674 M, the concentration of PH3 dropped to 0.0104 M after 67.0 s had passed. Based on this experiment, the rate constant for the reaction is
