What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy to its surroundings, usually in the form of heat.

Front

What is the significance of energy changes in chemical reactions?

Back

Energy changes determine whether a reaction is endothermic or exothermic, affecting temperature and spontaneity.

Front

How can you identify an exothermic reaction in a lab?

Back

By feeling a temperature increase in the reaction mixture.
