The potential energy diagram should show the activation energy (labeled as 50 kJ/mol), the change in enthalpy (double arrow labeled as -10 kJ/mol), and the activated complex location, with axes labeled "Reaction Progress" and "Potential Energy."
The potential energy diagram visually represents the energy changes that occur during a chemical reaction. The horizontal axis is labeled as "Reaction Progress," indicating the stages of the reaction, while the vertical axis is labeled as "Potential Energy," denoting the energy content of the system. The activation energy, representing the energy required to initiate the reaction, is marked with an upward arrow and labeled as 50 kJ/mol.
A double arrow signifies the change in enthalpy, indicating a decrease in energy by -10 kJ/mol during the reaction. The activated complex, a transitional state in the reaction, is located appropriately on the potential energy curve. This diagram provides a graphical representation of the energy profile of the reaction, illustrating key parameters such as activation energy, change in enthalpy, and the progression of the reaction over time.
