A
dH=Hp-Hr
dH=q
heat of reaction
3
Q
q formula
A
q=msdT
qsyst=-qreaction
4
Q
Hess law
A
Enthalpy of a reaction is the same wether in 1 or multiple steps
if reaction reverse, sign of dH is reversed
magnitute of dH proportional to quantity of reactants and products in a reactions, if multiplied by integer, dH also multiplied by interger
5

A
pressure of pure gas (if gaseous) liquid or solid at 1 atm and 25C
if solution, at 1M, same as solid, etc
