27. Using the data provided, calculate the multiple bond energy ( $\mathrm { kJ } \mathrm { mol } ^ { - 1 }$ ) of a $\mathrm { C } \equiv \mathrm { C }$ bond in $\mathrm { C } _ { 2 } \mathrm { H } _ { 2 }$. That energy is (take the bond energy of a $\mathrm { C } - \mathrm { H }$ bond as $350 \mathrm {~kJ} \mathrm {~mol} ^ { - 1 }$.)\\
$2 \mathrm { C } ( \mathrm { s } ) + \mathrm { H } _ { 2 } ( \mathrm {~g} ) \longrightarrow \mathrm { C } _ { 2 } \mathrm { H } _ { 2 } ( \mathrm {~g} )$

$$\begin{aligned}
& \Delta H = 225 \mathrm {~kJ} \mathrm {~mol} ^ { - 1 } \\
& \Delta H = 1410 \mathrm {~kJ} \mathrm {~mol} ^ { - 1 } \\
& \Delta H = 330 \mathrm {~kJ} \mathrm {~mol} ^ { - 1 }
\end{aligned}$$
