... - Exothermic reactions have negative DHrxn values -Typically (but not always) spontaneous reactions have negative values of DHrxn (the heat term is added to the products side) - We express enthalpy for a chemical reaction (DHrxn) as a stoichiometric component in a thermochemical equation 2H2O(l) 2 ...
