【正文】 atalyst a different colour at the end of the experiment than at the beginning? 7. What colour was the activated plex? 8. Illustrate the affect the catalyst had on the reaction (using both Ek and Ep diagrams) Answers 1. The production of CO2 (bubbling) is a physical sign that the reaction is occurring 2. The reactants are colourless 3. CoCl2 was the catalyst in the lab (pink, homogenous) 4. There was no reaction because the Ea was not reached (Illustrate with a Ek diagram). 5. The reaction still slow after heat is added because very few molecules exceed Ea. Fraction of molecules Kiic energy ? Answers 6. The catalyst was the same colour at the end of the experiment (catalysts don’t change). 7. The activated plex was green 8. Illustrate the affect the catalyst had on the reaction (using both Ek and Ep diagrams) Fraction of molecules Kiic energy ? potential energy Path of reaction For more lessons, visit
