To find the equilibrium constant, the changes in concentration of reactants and products need to be calculated using the ICE table method, followed by applying the equilibrium constant expression which is based on the stoichiometry of the given reaction.
Step-by-step explanation:
The question asks to calculate the value of the equilibrium constant (Kc) for the reaction given that at equilibrium, the concentration of A is 0.134 M, with initial amounts of 1.1 mol A and 7.5 mol B in a 5 L container. To solve this, we need to calculate the changes in concentration of reactants and products when equilibrium is re-established after adding more of compound A. This requires an assumption about the stoichiometry of the reaction, which is not provided in the question. However, a hypothetical stoichiometry may be used, such as a 1:1 ratio between A and B, to demonstrate how to use the ICE (Initial, Change, Equilibrium) table for solving equilibrium problems. Once the equilibrium concentrations are known, the equilibrium constant can be calculated using the formula Kc = [Products]n / [Reactants]m, where n and m are the stoichiometric coefficients in the balanced chemical equation and the brackets denote the concentrations of the products and reactants at equilibrium.
