• A)The system is at equilibrium, thus no concentration changes will occur.
• B)The concentrations of HI and I₂ will increase as the system approaches equilibrium.
• C)The concentration of HI will increase as the system approaches equilibrium.
• D)The concentrations of H₂ and HI will fall as the system moves toward equilibrium.
• E)The concentrations of H₂ and I₂ will increase as the system approaches equilibrium.
