7 The equation for the complete combustion of 2-methylpropan-2-ol is CHOM + 60,19) 4CO2(g) +SH,00) 6) Using the bond enthalpies shown in the table, calculate a value for the enthalpy change, in kl mol for the complete combustion of 2-methylpropan-2-ol. (4) Bond Mean bond enthalpy / kJ mol 347 CC CH 413 6-O 358 он 464 оо 498 со 805

(1) 2-methylpropan-2-ol burns in air with a smoky flame. Explain how burning with a smoky flame affects the value of the experimentally determined enthalpy change of combustion (2) (10) A Data Book value for the enthalpy change of combustion of 2-methylpropan-2-ol is-2643,8 kJ mol. Give the main reason for the difference between this value and your answer to part 7(c)0). TOTAL FOR PAPER = 40 MARKS
