enthalpy of reaction
« on: August 02, 2005, 12:45:17 AM »
I've been puzzled by the true meaning of enthalpy of reaction. Enthalpy of formation of compound is enthalpy generated to produce 1 mole of that compound.

So when you have a reaction

aA + bB -> cC + dD

Does the enthalpy of reaction really means change in enthalpy when "a" mole of A and "b" mole of B are consumed to produce "c" mole of C and "d" mole of D or does it really means enthalpy change until the equalibrium constant is reached?
