Lab 9 Heat of Reaction
OBJECTIVE:
To experimentally determine the heat of reaction for two
exothermic reactions.
DISCUSSION:
The heat given off or gained in a reaction is called the heat
of reaction (∆?????????).
A reaction that releases heat is known as an exothermic
reaction; an endothermic reaction
is one that absorbs heat.
The heat of the reaction corresponds to one mole of the
reactant and is expressed in
kilocalories per mole of reactant or in kilojoules per mole of...
