3 a) What is meant by the term enthalpy at formation. standard state b) The enthalpies of combustion of carbon, hydrogen and ethanol are given below. Co+Ow *CO AH--393kJ/mol H+O+H₂O AH-286 kJ/mol (1) If the enthalpy of combustion of ethanol is-1369kJ/mol. Draw the energy cycle diagram that links the enthalpy of formation of ethanol to enthalpies of combustion of carbon and hydrogen. (3) c) Study the information in the table below and answer the questions that follow. BOND ENERGY (kJ/Mol) 414 326 244 431 BOND C-H C-CI CI-CI H-C1 Calculate the enthalpy changes for the reaction below. CH₂Cl +Cla U.V. light CH₂Cl + HCl (3 mks) d) At standard temperature and pressure graphite changes to diamond as shown in the equation below. Campi CAH+2.91kg/mol Sketch a simple energy level diagram for the above change. 3 a) What is meant by the term enthalpy at formation. standard state b) The enthalpies of combustion of carbon, hydrogen and ethanol are given below.
