A scientist measures the standard enthalpy change for the following reaction to be -2929.4 kJ :2C2H6(g) + 7 O2(g)4CO2(g) + 6 H2O(g)Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of CO2(g) is kJ/mol.
The standard molar enthalpy of formation of diborane, B₂H₁ (g), cannot be determined directly because the compound cannot be prepared by the reaction of boron and hydrogen. It can be calculated from other enthalpy changes, however. The following enthalpy changes can be measured. 4 B(s) + 3 O₂ (g) → 2 B₂O3 (s) A₁H° = -2543.8 kJ/mol-rxn H₂(g) + 1/2 O₂ (g) → H₂O(g) A, H = -241.8 kJ/mol-rxn B2 H6 (g) + 3 O2 (g) → B₂O3 (g) + 3 H₂O(g) A₁H° = −2032.9 kJ/mol-rxn a we will show how these equations can be added together to give the equation for the formation of B₂ H6 (g) from B(s) and H₂(g) in their standard states and determine the enthalpy of formation. The target reaction is 2 B(s) + 3 H₂(g) → B2H6 (g) Does Reaction 1 need to be used as is, or reversed? as is reversed The reaction is used as is because B(s) is a reactant in the target reaction and in Reaction 1.
