Consider these three reactions as the elementary steps in the mechanism for a chemical reaction.(i) Cl (g) + Pt (s) 2CI (g) + Pt (s)(ii) Cl (g) + CO (g) + Pt (s) CICO (g) + Pt (s)(i) Cl (g) + CICO (g) CICO (g)Ea = 1550 kJEa = 2240 kJEa = 2350 kJAH = - 950 kJAH = 575 kJ = - 825 kJa. Draw the potential energy diagram for the reaction. Label the data points for clarity.The potential energy of the reactants is 600 kJ (6T)b. What is the overall chemical equation? (1T)c. What is the overall change in enthalpy for the above chemical reaction? (1T)d. What is the overall amount of activation energy for the above chemical reaction? (1T)e. Which reaction intermediate would be considered a catalyst (fany) and why? (2 T)f. If you were to add 2700kJ of energy to the reaction (e.g. 2700 kJ of heat or electricity), would you be able to make the reaction reverse itself (i.e. have the products become reactants)?Justify your answer. (2 A)8. If you were to added a positive catalyst to step (ii) what would the end result be? Explain your prediction. (2 C)h. Your friend is looking at your graph and states that she believes that step (ii) is the rate determining step. Do you agree with her? If you do not agree with her, what step would you pick as the RDS? (3 C)
