What happens to the equilibrium constant when a reaction is multiplied by a factor? (2023)

Step 1: Start with a balanced chemical equation and its equilibrium constant (K).
Step 2: If you multiply the entire balanced equation by a factor (let's say 'n'), you need to consider how this affects the equilibrium constant.
Step 3: The equilibrium constant (K) is related to the concentrations of the products and reactants in the reaction.
Step 4: When you multiply the equation by 'n', you are effectively increasing the coefficients of the reactants and products by 'n'.
Step 5: The new equilibrium constant (K') is calculated by raising the original equilibrium constant (K) to the power of 'n'.
Step 6: Therefore, K' = K^n, where K' is the new equilibrium constant after multiplying the equation.

Equilibrium Constant Adjustment – The equilibrium constant changes based on the stoichiometric coefficients of the balanced chemical equation.
