In a certain manufacturing plant, material A is to be reacted (at constant pressure) as one of the important processes, as shown below: A₍ₛ₎ + 2B₍ₗ₎ → 2C₍ₗ₎ + 2D₍ₛ₎ For the reaction to proceed, heat is needed. The reaction will be processed inside a chemical reactor that stirs the reactants and supplies heat. The heat supply for the chemical reactor is electrically operated and runs at 220 volts and 10 amperes. Heat-voltage-current relationship is given below: Q = VIt Where: Q = sensible heat in kJ V = voltage in volts I = current in amperes t = time in seconds Also: 1 kJ = 1 V-amp The chemical reactor can handle 888 moles of A only at a time (that's one batch). After the batch's reaction has finished, the contents of the chemical reactor is being emptied and another batch is being filled in the chemical reactor. If the plant has allotted a total of 2 hours for this process, how many batches can be catered by this chemical reactor? The heat of formation of the above chemical species are below: A₍ₛ₎ = 250 kJ/mol B₍ₗ₎ = 600 kJ/mol C₍ₗ₎ = 500 kJ/mol D₍ₛ₎ = 750 kJ/mol
