C. e) The only bromine-containing product of the complete combustion of compound C is bromine (Br2). Write a balanced reaction, including state symbols, for the complete combustion of compound C in oxygen. Assume that compound C is in a crystalline form. (3 marks) Question continued on the next page Page 4 of 5 f) Use your answer for part (e) to state whether the change in entropy ( S ) for the complete combustion of compound C in oxygen is positive or negative, briefly explaining your answer. (2 marks) g) Use your answer to part (e) to determine: (i) the work done, and (ii) the change in internal energy during the complete combustion of 0.168g of compound C in oxygen assuming a constant external pressure and a temperature of 298K. Assume that the molar enthalpy of combustion of compound C is an exothermic process with an enthalpy change of 313kJmol1
