Molecular hydrogen gas and molecular iodine gas react according to the following balanced equation:?2(?) + ?2(?) ⇌ 2 ??(?)A reaction mixture at equilibrium at 175 K contains PH2 = 0.958 atm, PI2 = 0.877 atm, and PHI = 0.020 atm. A second reaction mixture, also at 175 K, contains PH2 = PI2 = 0.621 atm, and PHI = 0.101 atm. Is the second reaction at equilibrium?

Question

Molecular hydrogen gas and molecular iodine gas react according to the following balanced equation:

?2(?) + ?2(?) ⇌ 2 ??(?)

A reaction mixture at equilibrium at 175 K contains PH2 = 0.958 atm, PI2 = 0.877 atm, and PHI = 0.020 atm. A second reaction mixture, also at 175 K, contains PH2 = PI2 = 0.621 atm, and PHI = 0.101 atm. Is the second reaction at equilibrium? If not, what will be the partial pressure of HI when the system reaches equilibrium at 175 K?
