Graph exothermic reaction
WebJun 22, 2024 · Exothermic Reaction Graph. All chemical reactions involve a change in energy, and an energy diagram (graph) represents this change. In the exothermic … WebIn an endothermic reaction, ΔH Δ H is greater than zero because the energy of the reactants is less than the energy of the products. Energy is absorbed in the reaction. For example: C (s) + H2O (l) → CO (g) + H2(g) ΔH > 0 C (s) + H 2 O (l) → CO (g) + H 2 (g) Δ H > 0. Some of the information relating to exothermic and endothermic ...
