Reaction profile of endothermic reaction

WebAn endothermic reaction is a chemical reaction that requires energy in the form of heat. This means that the energy of the products is higher than the energy of the reactants. These questions and answers can help students understand reaction profiles and activation energy in GCSE chemistry and prepare them for their exams.
