The kinetics of the decomposition of phosphine at 950 K
4PH3 (g) -> P4 (g) + 6H2 (g)
was studied by injecting PH3(g) into a reaction vessel and measuring the total pressure at constant volume.
P total (Torr) Time (s)
What is the rate constant of this reaction?
PV = nRT
rate = k[PH3] ^n
The Attempt at a Solution
Do I need to find the reaction order with respect to PH3 before finding the rate constant? I am lost.
