Chapter 6.6, Problem 9PE

Calculate the standard enthalpy of formation of carbon disulfide (CS₂) from its elements, given that

$\begin{array}{cc}\text{C}(\text{graphite})+{\text{O}}_2(g)\stackrel{}{\to }{\text{CO}}_2(g)& \Delta H_{\text{rxn}}^0=-393.5\text{kJ/mol}\\ \text{S}(\text{rhombic})+{\text{O}}_2(g)\stackrel{}{\to }{\text{SO}}_2(g)& \Delta H_{\text{rxn}}^0=-296.4\text{kJ/mol}\\ {\text{CS}}_2(l)+3{\text{O}}_2(g)\stackrel{}{\to }{\text{CO}}_2(g)+2{\text{SO}}_2(g)& \Delta H_{\text{rxn}}^0=-1073.6\text{kJ/mol}\end{array}$
