Measurement of an Equilibrium Constant Introduction: Most chemical reactions (e.g., the "generic" A + B 2C) are reversible, meaning they have a forward reaction (A + B forming 2C) and a backward reaction (2C forming A+ B). How do you explain the difference in catalytic activity of the fresh and boiled potatoes? To re-establish equilibrium, the system will either shift toward the products (if Q < K) or the reactants (if Q > K) until Q returns to the same value as K. This process is described by Le Chtelier's principle: When a chemical system at equilibrium is disturbed, it returns to equilibrium by counteracting the disturbance. The case depth is defined as the distance below the surface that contains at least 0.5%C0.5 \% \mathrm{C}0.5%C. The expression for the equilibrium constant for a reaction is determined by examining the balanced chemical equation. The color should become more .
