ChemistryWiki | RecentChanges | Preferences

1. For an Endothermic reaction, the Potential Energy of the reactant (PEr) is greater than, less than or equal to (circle one) the Potential Energy of the product (PEp)?

2. On the Potential Energy diagram of an Exothermic reaction, what represents the Activation energy of the reaction?


3. A "-" sign of the heat of reaction (ΔH) indicates that the energy is being ___________ by the reaction (also called the system).


4. Define Activation Energy.



5.On the Potential Energy diagram, where is the location of the Potential Energy of the Activated complex and what two energies (hint: one is a Potential Energy) make up the Potential Energy of the Activated complex.
