Question details

Question 4 The decomposition of phosphine (PH3) to phosphorus vapour (P4) and hydrogen is to take place in a plug flow reactor at a constant temperature of 925 K. The feed rate of PH3 and the pressure are constant a) Build a stoichiometric table showing molar flowrate at any conversion, X, indicate the initial total number of molar flow rate, FTo, and total number of molar flow rate, FT and evaluate numerically δ, and ε. 15 Marks] b) For a conversion of 50% of PH3, calculate the residence time (t) in the reactor and the space-time (i) and briefly explain between any differences. Assume the rate of decomposition is proportional to the concentration of PH3 at any point, with a proportionality constant k 3.6 x 10-3 s-7 at 925 K. [15 Marks]
