Standard Reaction Enthalpy Property

Postby SoJeong Lee » Fri Jan 13, 2017 11:05 pm

What is the main difference between a standard reaction enthalpy and a standard reaction enthalpy of formation?

Based off the notes on page 17, I'm pretty sure there isn't much difference except for the fact that standard reaction enthalpy of formation is for one mole of a substance.

Standard reaction enthalpies refer to the changes in enthalpy for an entire reaction when the reactants change into products. Standard enthalpies of formation refer to the change in enthalpy for a particular substance (e.g. one particular reactant or one particular product) which are then added/subtracted in order to find the change in enthalpy for the entire reaction.
