(a) A chemical engineer studying the properties of hydrocarbon placed 10.0g of propane, C3H8, in a bomb calorimeter. The temperature of the bomb calorimeter rise from 20.0C to 36.2C. If the heat capacity of the bomb calorimeter is 31.4kJCC1, (i) Determine the heat of combustion of propane. (ii) Write the thermochemical equation for combustion of propane. [5 marks] (b) (i) Define lattice energy. (ii) Based on the data in TABLE 2, construct the Born-Haber cycle for lithium chloride and calculate its lattice energy. TABLE 2 [5 marks]
