The enthalpy changes of the following reactions can be measured: (a) Use these values and Hesss law

Question:

The enthalpy changes of the following reactions can be measured:

CH,(g) + 3 O2(g) 2 CO2(g) + 2 HO(0) = -1411.1 kJ/mol-rxn CH,OH(0) + 3 O2(g) 2 CO2(g) + 3 H2O(0) = -1367.5

(a) Use these values and Hess’s law to determine the enthalpy change for the reaction

(b) Draw an energy level diagram that shows the relationship between the energy quantities involved in this problem.
