At some temperature, the equilibrium constant for the reaction H2 (g) + 12 (g) 2HI (g) is Kp = 25. A closed vessel at 298 K is charged with 2.00 atm of H2 (g), 2.00 atm of I2 (g), and 1.00 atm of HI (g). Use Q to determine which of the statements below is true. O At equilibrium, the total pressure in the vessel will be less than the initial total pressure. O The equilibrium partial pressure of H2 will be greater than 2.00 atm. O The equilibrium partial pressure of H2 (g) will be 0.5 atm. The reaction will go to completion since there are equal amounts of H2 and 12. O The reaction is at equilibrium
