Consider the following reaction and its equilibrium constant: I₂(g) ⇌ 2I(g) K_p = 0.209
A reaction mixture contains 0.89atm I₂ and1.53 atm I.Which of the following statements is TRUE concerning this system?

Question

Quizplus · Accepted Answer

To determine the direction of the reaction, we need to compare the reaction quotient (Q) with the equilibrium constant (K). Q = (I)^2 / (I₂) = (1.53 atm)^2 / (0.89 atm) = 2.63 atm Since Q > K, the system is not at equilibrium, and the reaction will shift in the direction of reactants to decrease Q and approach equilibrium. Therefore, the correct choice is A.
