# The energy change of the reaction  $C_2H_6(g) \rightarrow 2C(g) + 6H(g)$  is $x\: kJ$. The bond energy of $C-H$ bond is

$\begin {array} {1 1} (A)\;x/6\: kJ & \quad (B)\;x/3\: kJ \\ (C)\;x\: kJ & \quad (D)\;data \: insufficient \end {array}$

Calculation of $\Delta H_{C-H}$ requires the value of $\Delta H_{C-C}$ also which is not given.
Ans : (D)
