QUESTION 5 [Marks 251 The reaction mixtures consist of 76,94% A with 23.065 inert at 101.325 kPa and 287 K. The reaction is initiated by dropping the reactor into a constant temperature bath at 373 K. The equilibrium calculations have shown the reaction to be essentially irreversible in this temperature range. The partial pressure relationship of A with the total pressure of reactant is given by: Pa = Pxo - (P. P.) Where Pro = initial partial pressure of reactant A = the molar stoichiometry coefficient of reactant A = change in the number of moles P-total pressure, kPa Po = initial total pressure, kPa a RT The reaction equation is given by: A 2B Determine, using the graphical differential method the appropriate expression for the gas-phase reaction, utilizing the following data from a constant-volume batch reactor. Time (h) Total pressure (kPa) 0 56 8 132.7 167.2 186.4 197.6 205,2 210.8 214.8 220.4
