5 mol% of aqueous sulfuric acid (H2SO4) solution at 25 C and 40 mol% of aqueous H2SO4 solution at 15 C are mixed to form a 20 mol% of aqueous H2SO4 solution. The product solution temperature is eventually kept at 25C. a) Draw and label the diagram of the process completely. (3 marks) b) Calculate the heat (kJ) that must be transferred from every 1 mol of the 20 mol% product solution prepared. The heat capacity of the 40 mol% aqueous H2SO4 solution is to be 75.4 kJ/mol.C. Clearly state the basis of calculation and reference state used in constructing the enthalpy table. (12 marks)
