Consider the following balanced reaction:

$\displaystyle {2}\text{A}_{{2}}+{3}\text{B}\to\text{C}_{{2}}+{2}\text{D}$

What is the enthalpy of reaction if the enthalpy of formation of the compounds is given as $\displaystyle \text{A}_{{2}}$ = 9.6 kJ/mol; B = -13.47 kJ/mol; $\displaystyle \text{C}_{{2}}$ = 0 kJ/mol; D = 24.01 kJ/mol.
