In a Study of the System, H₂(g)+ I₂(g) 2

In a study of the system, H₂(g) + I₂(g) 2 HI(g) , at 699 K, several different reaction mixtures, described below, were prepared, placed in 5.00 liter containers, and allowed to attain equilibrium at 699 K. Despite having the different starting compositions shown, four of the five mixtures had the identical composition at equilibrium. Which one of the systems attained a different equilibrium composition than the others?

A) System 1: 0.100 moles of H₂, 0.000 moles of I₂ and 0.600 moles of HI
B) System 2: 0.175 moles of H₂, 0.075 moles of I₂ and 0.450 moles of HI
C) System 3: 0.400 moles of H₂, 0.300 moles of I₂ and 0.000 moles of HI
D) System 4: 0.150 moles of H₂, 0.100 moles of I₂ and 0.500 moles of HI
E) System 5: 0.300 moles of H₂, 0.200 moles of I₂ and 0.200 moles of HI
