Which of the following process best describes atomization of $C{H}_4\left(g\right)?$

The standard heat of formation of ${\mathrm{CH}}_4, {\mathrm{CO}}_2$ and ${\mathrm{H}}_2\mathrm{O}$ are $-762,-394.8$ and $-285.82 \mathrm{kJ}{ \mathrm{mol}}^{-1},$ respectively. Heat of vaporisation of water is $44 \mathrm{kJ}{ \mathrm{mol}}^{-1}.$ Calculate the amount of heat eveolved when $22.4 \mathrm{L}$ of ${\mathrm{CH}}_4,$ kept under normal conditions, is oxidized into its gaseous products.

One mole of ethanol is produced reacting graphite, $H_2$ and $O_2$ together. The standard enthalpy of formation is $-277.7 kJ mo{l}^{-1}.$ Calculate the standard enthalpy of the reaction when $4$ moles of graphite is involved

Which of the following can help predict the rate of a reaction if the standard Gibbs free energy of reaction $\left(\Delta G^0\right)$ is known?
