You can determine whether a reaction is endothermic or exothermic by observing the temperature change of the surroundings or by considering the enthalpy change ( H) of the reaction. Exothermic Reactions: Observation: The surroundings (e.g., the solution in a beaker, the air around the reaction) will increase in temperature. You will feel the reaction vessel get hotter. This is because the reaction releases heat energy* into the surroundings. Enthalpy Change: For an exothermic reaction, the enthalpy change ( H) is negative* ( H < 0). This means the products have lower energy than the reactants. Endothermic Reactions: Observation: The surroundings will decrease in temperature. You will feel the reaction vessel get colder. This is because the reaction absorbs heat energy* from the surroundings. Enthalpy Change: For an endothermic reaction, the enthalpy change ( H) is positive* ( H > 0). This means the products have higher energy than the reactants.
