A continuous reactor containing aqueous sulphuric acid is to be neutralised using aqueous sodium hydroxide. The sulphuric acid is added at 40C and the sodium hydroxide at 25C. The product solution emerges at 35C. The extent of reaction () is 1.02 . Given data: H2SO4(aq)+2NaOH(aq)Na2SO4(aq)+H2O(l) The aqueous sulphuric acid and sodium hydroxide concentrations are 15.0wt%. a) Compute the material balance including amount of water formed for the process. [4 marks] b) Calculate the rate in kJ/kg sulphuric acid solution must heat be removed from reactor for product solution to emerge at 35C. [6 marks]
