WebEndothermic, the products have more energy than the reactants. b) On the diagram provided in your answer booklet,draw a dashed line to indicate a potential energy curve for the reaction if a catalyst is added. Answer--> Can't, but you can make the … WebIn this diagram, the activation energy is signified by the hump in the reaction pathway and is labeled. At the peak of the activation energy hump, the reactants are in the transition …

6.2.3.3: The Arrhenius Law - Activation Energies

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 http://www.kentchemistry.com/links/Kinetics/PEDiagrams.htm body kindergarten activities

WebJun 22, 2024 · Endothermic Reaction Graph. We can represent the endothermic reaction through a graph called an energy diagram. The x-axis shows the time, and the y-axis represents the potential energy. The graph shows the change in energy. When a substance absorbs energy during the reaction, the enthalpy (\(\triangle H\)) changes. We can see … WebThe graph below illustrates a change in energy during a phase change. Which explanation correctly describes the phase change in the graph? This is an exothermic reaction that involves freezing. This table has information about the heat of fusion and the heat of vaporization of different substances. WebDec 20, 2015 · An endothermic reaction must have a positive change in enthalpy. That is, ΔH > 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. bodykind voucher code
