Enthalpy Change
-
-
-
standard enthalpy change
D: change in heat energy at constant
pressure, measured at standard conditions
-

-
Exothermic Reactions
-
-
chemical energy transferred
to heat energy which is released
- giving INCREASE in TEMP in
surroundings
-
examples -
- combustion - burning fuels for heating
- respiration - oxidation of carbohydrates
in living things
-
-
Endothermic Reactions
-
-
heat energy transferred to
chemical energy
- observable DECREASE in TEMP
