$$ \ce{CO(g) + 2H(g) <--> CH3OH(g)} \hskip{2em} \Delta H \lt 0 $$
Which of the following statements is true about bond energies in this reaction?
Energy is absorbed in order to break bonds. Energy is released when bonds are formed.
Enthalpy is related to bond formation and breaking by:
$$ \Delta H = \sum \Delta H_{\text{bonds broken}} - \sum \Delta H_{\text{bonds formed}} $$
Since \(\Delta H\) is negative,
$$ \Delta H \lt 0 $$
$$ \sum \Delta H_{\text{bonds broken}} - \sum \Delta H_{\text{bonds formed}} \lt 0 $$
$$ \sum \Delta H_{\text{bonds broken}} \lt \sum \Delta H_{\text{bonds formed}} $$
