The irreversible liquid-phase A to B is carried out in a batch reactor of volume 2000 dm3 operating at 473 K. Only A and a small amount of solid catalyst are present initially. The initial concentration of A is 2.8 mol dm-3. The reaction is second order in A. The following parameters have been determined experimentally:

A0 = 8000 dm3 mol s-1

EA = 70 kJ mol-1

∆H = -40 kJ mol-1

The solution has a constant density of 0.95 g cm-3, while the heat capacity remains constant at 0.005 kJ g-1 K-1

a) What is the conversion of A when the concentration of B reaches 1.2 mol dm-3? State your value as percentage to two significant figures

b) Determine after what time a conversion of 60% is achieved

c) If the reactor is instead operated adiabatically then what temperature will the solution be at when the conversion is 60%?
