1.The thermal decomposition of phosphine (PH3) into phosphorus and molecular hydrogen is a first-order reaction:4PH3(g) → P4(g) + 6H2(The half-life of the reaction is 35.0 s at 680°C. Calculate (a) the first-order rate constant for the reaction and (b) the time required for 95 percent of the phosphine to decompose. (10 points) g )
