Consider the following reaction and its equilibrium constant: I₂(g) + Br₂(g) ⇌ 2IBr(g) K_c = 1.1 × 10²
A reaction mixture contains 0.41 mol L^-1 I₂, 0.27 mol L^-1 Br₂and 3.5 mol L^-1 IBr. Which of the following statements is TRUE concerning this system?

Question

Quizplus · Accepted Answer

The system is already at equilibrium because the given number of moles of reactants and products satisfy the equilibrium constant (Kc = 1.1 × 10^12). Therefore, there will be no shift in the direction of products or reactants, and the reaction quotient will remain equal to the equilibrium constant. The equilibrium constant will also remain unchanged.

Consider the Following Reaction and Its Equilibrium Constant: I2(g)

Consider the Following Reaction and Its Equilibrium Constant: I₂(g)
