From the following data, C(graphite) + O2(g) → CO2(g) ΔH°rxn = −393.5 kJ/mol H2(g) + 1/2 O2(g) → H2O(l) ΔH°rxn = −285.8 kJ/mol 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(l) ΔH°rxn = −3119.6 kJ/mol calculate the enthalpy change for the reaction below: 2 C(graphite) + 3H2(g) → C2H6(g) kJ

Use Hess' law and the following thermochemical equations to produce the thermochemical equation for the reaction $\mathrm{C}(\mathrm{s},$ diamond) $\rightarrow \mathrm{C}(\mathrm{s},$ graphite).What is $\Delta H$ for the reaction? $$ \begin{array}{ll}{\text { a. } \mathrm{C}(\mathrm{s}, \text { graphite })+\mathrm{O}_{2}(\mathrm{g}) \rightarrow \mathrm{CO}_{2}(\mathrm{g})} & {\Delta H=-394 \mathrm{kJ}} \\ {\text { b. } \mathrm{C}(\mathrm{s}, \text { diamond })+\mathrm{O}_{2}(\mathrm{g}) \rightarrow \mathrm{CO}_{2}(\mathrm{g})} & {\Delta H=-396 \mathrm{kJ}}\end{array} $$
