1. A 200dm3 constant volume batch reactor is pressurized to 20atm with a mixture of 75% A and 25% inert. The gas phase reaction AB is carried out isothermally at 227C. [3+5] a) Assuming that the ideal gas law is valid, how many moles of A are in the reactor b) If the reaction is second order, calculate the time required to consume 80% of A. The initially? What is the initial concentration of A ? reaction rate constant, k=0.7dm3/mol.min
