Energy in Chemical Reactions I Unit Test Flashcards | Quizlet It is an endothermic reaction because the system takes energy from the surroundings. A student pours ammonium nitrate into a container of room temperature water. The student stirs the mixture with a stirring rod and then feels the outside of the container, which is cold to the touch. How can I represent an endothermic reaction in a potential ... An endothermic reaction must have a positive change in enthalpy. That is, Delta"H">0. This means that the system absorbs heat. To represent the positive change in enthalpy, the potential energy of the reactants must be LOWER than that of the products. Notice how the end of the "hump" is higher than the beginning, showing how the system gained energy during the course of the reaction. Energy Profiles (Energy Diagrams) Chemistry Tutorial Energy Profile for Endothermic Reactions We saw above that the synthesis of ammonia gas from nitrogen gas and hydrogen gas was an exothermic process: N 2 (g) + 3H 2 (g) → 2NH 3 (g) + 92.4 kJ mol -1 and we constructed an Energy Profile to show the relative enthalpies of reactants and products. 18.4: Potential Energy Diagrams - Chemistry LibreTexts A potential energy diagram shows the change in potential energy of a system as reactants are converted into products. The figure below shows basic potential energy diagrams for an endothermic (A) and an exothermic (B) reaction. Recall that the enthalpy change ( Δ H) is positive for an endothermic reaction and negative for an exothermic reaction.
