2. Draw the potential energy diagram for an exothermic reaction and define each section of the diagram. Show where the heat of reaction deltaHrxn is located on the graph and explain how you calculate it. Then show on the graph and through effective collisions how adding a catalyst increases rate of the reaction.
3. A one liter (1L) container holds 1.45moles of nitrogen gas and 0.650mole of oxygen gas. What is the equilibrium concentration of all the species if the equilibrium constant is equal to 1.25 (K=1.25) for the following balanced chemical reaction,
