Question

If heat of atomisation of ${CH}_{4} (g)$ is $1665 kJ {mol}^{- 1}$ then the bond energy of $C - H$ bond (in $kj {mol}^{- 1}$ ) will be

Open in App

Solution

Step 1: Calculating the bond energy
We have, $\underset{Methane}{{CH}_{4} (g)} \to \underset{Carbon}{C (g)} + \underset{Hydrogen}{4 H (g)}$
Here in this reaction, the enthalpy of atomization is $∆ H = 1665 kJ {mol}^{- 1}$
$∴$ The bond energy $C - H$ is
$\frac{1665}{4} = 416.2 kJ mol$
Therefore the bond energy of $C - H$ is $416 kJ mol$
