Heat of Formation

Molar Heat of Formation

$\Delta H$ that accompanies the formation of 1 mole of a compound from its elements You will be given a table of heat of formation values

NOTE

$\mathrm{C}{}_{(\mathrm{s})}+\mathrm{O}{}_{2(\mathrm{s})}\to \mathrm{CO}{}_{2(\mathrm{g})}$

For any reaction: $aA+bB\to cC+dD$ $\Delta H_r°=\sum \Delta H_f°(\text{products})-\sum \Delta H_f°(\text{reactants})$
