10 POINTS FOR CORRECT ANSWERS.
1.) What is the relationship between the classification of a reaction as endothermic or exothermic and the enthalpy of the reaction?
2.)Chemicals combine in instant cold packs and the temperature of the mixture decreases. Is this an exothermic or endothermic process?

-
1.)If the enthalpy of the reaction is -ve then the reaction is exothermic
If the enthalpy of the reaction is +ve then the reaction is endothermic
2.) Since the products obtained are colder than reactants,it is endothermic.
If the enthalpy of the reaction is +ve then the reaction is endothermic
2.) Since the products obtained are colder than reactants,it is endothermic.
