ENDO/EXOTHERMIC REACTIONS
, AIMS
Distinguish between exothermic and endothermic reactions on the basis of th
temperature change of the surroundings.
Evaluate uses and applications of exothermic and endothermic reactions give
appropriate information.
Know which variables affect temperature changes in reacting solutions such a
plus metals.
Draw simple reaction profiles (energy level diagrams) for exothermic and
endothermic reactions showing the relative energies of reactants and produc
activation energy and overall energy change.
Use reaction profiles to identify reactions as exothermic or endothermic.
Explain that the activation energy is the energy needed for a reaction to occur
, EXOTHERMIC REACTIONS
An exothermic reaction is one where energy is transferred to th
surroundings and the temperature of the surroundings increase
In exothermic reactions, energy exits.
The overall energy change in the reaction is negative as energy
been lost from the reaction to the surroundings.
Examples – combustion, many oxidation reactions and most
neutralisation reactions.
