Solution: The thermal decomposition of phosphine (PH3) into
Chapter 13, Problem 12.26(choose chapter or problem)
The thermal decomposition of phosphine \(PH_3)\ into phosphorus and molecular hydrogen is a first-order reaction:
\4PH_3(g) + P_4(g) \rightarrow 6H_2(g)\
The half-life of the reaction is 35.0 s at \680^oC\. Calculate
(a) the first-order rate constant for the reaction and (b) the time required for 95 percent of the phosphine to decompose.
