In endothermic reactions the reactants have higher bond energy stronger bonds than the products. Test tubes Thermometers Reagents. By knowing how to draw and label an enthalpy diagram we can see what the starting energy level is how much energy.

Label ΔH as positive or negative. Draw a horizontal line from the highest part of the curve towards the vertical axis. Figure shows the energy level diagram for the reaction between methane and oxygen.

ΔH is measured in kJmol kilojoules per mole. This reaction is also exothermic because the energy of the products is lower than that of the. Exothermic vs Endothermic Reactions 2C.

In the case of an endothermic reaction the reactants are at a lower energy level compared to the productsas shown in the energy diagram below. It also shows the effect of a catalyst on the f.
