- How was Thin Layer Chromatography (TLC) used in organic synthesis reactions ? TLC is used to find the exact concentration of a catalyst in the reaction. TLC can speed up a reaction because silica gel is polar. TLC can separate components of a reaction mixture such as starting materials and products allowing the experimenter to identify what compounds are in the reaction mixture. TLC is used to find percentage yield of the reaction.Write the equilibrium expression K. for catalytic methanation. CO(g) + 3H2(g) CH4(g) + H2O(g) K(forward) = And write the K, for the reverse of catalytic methanation. CHĄ(g) + H20(g) 2 CO(g) + 3H2(g) K(reverse) =Write a balanced equation for the overall reaction.
