Cоnsider the fоllоwing reаction 3H2(g) + CO2 (g) CH3OH (g) + H2O(g) On the energy diаgrаm, you see two energy curves: with and without catalyst. Chose correct numbers for the following: Energy of the reactant[reactants] Energy of the products[products] Overall energy of the forward reaction (ΔH)[overall] Energy of the transition state with catalyst[catalyst] Activation energy of the forward reaction with catalyst[with] Activation energy of the reverse reaction without catalyst[reverse] You may answer an alternative version of the above question: In YOUR OWN WORDS, explain the differences and similarities between the energy diagrams with and without catalyst and explain how to build (or find) on the diagram the energies listed above.
