Questiоn 3 A student uses this аppаrаtus tо find the increase in temperature оf water when methanol, CH3OH, is burned. See diagram under the addendum Question 3 a The student records these results. Mass of burner and methanol before combustion 83.7g Mass of burner and methanol after combustion 82.2g Mass of water 110g Temperature of water at start 25oC Temperature of water at the end 59oC ai Calculate the heat energy change (Q), in joules, in this experiment using the expression (2) Q = m × 4.2 × ΔT where m is the mass of water in grams and ΔT represents the increase in temperature. aii The relative molecular mass of methanol is 32 (4) Use this information and your value for Q to calculate the molar enthalpy change, ΔH, for the combustion of methanol. Give your answer in kJ/mol. aiii The student draws an energy level diagram for the complete combustion of methanol. See addendum Question 3aiii (2) Identify the two mistakes in his diagram. b The student is given this table of average (mean) bond energies. Bond C-H C-O O-H O=O C=O Average bond energy in kJ/mol 413 362 460 494 742 The equation in the addendum under Question 3 b, for the complete combustion of methanol is given Use this equation and the information in the table to calculate another value for the molar enthalpy change, ΔH, for the combustion of methanol.
