Reaction Enthalpy

Postby Raul Davalos 1E » Sat Jan 21, 2017 3:22 pm

What information will be given for questions in which we have to determine enthalpy of a reaction?

Since there are three different ways to calculate the reaction enthalpy, the information that is given could be: 1) the summation reactions and each reactions enthalpy where we would use Hess's Law 2)the bond enthalpies where we would need to have a balanced equation or 3)standard reaction enthalpies (summation of enthalpies of the products - summation of enthalpies of the reactants). IN ALL CASES, keep in mind the moles needed in equations.
