The rate of the given reactions from graphs has to be ranked. The Δ H values for each reaction and which reaction is exothermic and which reaction is endothermic has to be determined. Concept introduction: Exothermic reaction: Exothermic reaction is said to be a chemical reaction in which energy will released in the form of heat. In general this reaction has to be represented as follows. Reactants → Products + Energy Endothermic reaction: Endothermic reaction is said to be a chemical reaction in which energy will consumed in the form of heat. In general this reaction has to be represented as follows. Reactants + Energy → Products
