Determine the equilibrium constant, K_eq, at 25°C for the reaction 2Br^-(aq)+ I₂(s)$\rarr$Br₂(l)+ 2I^-(aq)

Question

Quizplus · Accepted Answer

The equilibrium constant can be calculated using the equilibrium concentrations of the species involved. The coefficients in the balanced equation represent the stoichiometric ratios between the reactants and products. Therefore, the equilibrium constant expression is: K_eq = ([Br₂][I^{-]^2)/([}]^2) The concentrations can be determined using the initial concentrations and the extent of the reaction, which can be calculated from the stoichiometry of the reaction. However, the problem does not provide the necessary information to do so. Therefore, the question must be answered in terms of the given answer choices. By examining the answer choices, we see that choice A is the only answer in the correct format for an equilibrium constant expression. We can also check that the given expression matches the units of an equilibrium constant (M-2). Therefore, the answer is A.
