Question

How can we determine the difference between exothermic and endothermic reaction from an equation?

Answer 1

exothermic release of geat..

endothermic absorption of heat

Answer 2

Endothermic-Absorbs heat and requires heat and this reaction occurs in support of heat energy

Very often delta in 'give rise to' symbol resembles it is endothermic

Exothermic-Releases huge amount of heat when the reaction occurs

O2 on the reactant side means that the reaction occuring is exothermic

All combustion reactions are exothermic
