Measuring Energy Changes In A Chemical Reaction Sept. 2016
... Now that the units are “standardized” we call this energy change “enthalpy of the reaction”. Rather than using the symbol “q”, we use the symbol “ΔH”. Since heat has been lost by the system, it is an _________ reaction and we indicate this loss by using the (–)ve sign. Therefore: ΔH = -1561 kJ/mol ...
