Activation energy diagram worksheet

  • Another “Energy Diagram” • This is an example of a reaction that needs energy to get started. • The energy needed (a) is called the activation energy. • The reactants had 100 kJ of energy. • In the “activated complex” the chemicals had 400 kJ of energy. • After the reaction was fully
Activation energy 2 Activation energy 1 Transition state 1 Intermediate Heat of reaction Reaction coordinate Energ y Intermediate Reactants Products E a E a H this step crosses the higher energy barrier and therefore is the rate-determining step PROBLEM 5.1 In what way would the energy diagram drawn in Example 5.1 change if the reaction were ...

Label the x- and y-axes, the reactants, and the products on the diagram. Label the total change in enthalpy (Δ H) and activation energy (E a) on your diagram. Make sure correct units are included.

  • A. The activation energy is 10. kJ and the reaction is endothermic. B. The activation energy is 10. kJ and the reaction is exothermic. C. The activation energy is 50. kJ and the reaction is endothermic. D. The activation energy is 50. kJ and the reaction is exothermic. 17. Given the potential energy diagram of a chemical reaction:
  • The activation energy is the height between the substrate/reactant and the transition state. This is the height between the beginning and the highest point in the reaction energy diagram. The energy change between the reactants and products is the heat of reaction or change in enthalpy (∆H).
