1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction. (i) Cl₂(g) + Pt (s) → 2C) (g) + Pt (s) Ea = 1550 kJ (ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s) Ea - 2240 kJ ΔΗ = = 950 kJ ΔΗ = 575 kJ ΔΗ = = 825 kJ (iii) Cl (g) + CICO (g) → CI,CO (g) Ea - 2350 kJ 2600 2400 2200 2000 a. Draw the potential energy diagram for the reaction. Label the data points for clarity. The potential energy of the reactants is 600 kJ 1800 1600 1400 1200 1000 800 600 400 200 0 -200 -400 -600 -800- Reaction Progress b. What is the overall chemical equation? c. What is the overall change in enthalpy for the above chemical reaction?
