The system H2(g) + I2(g) ?? 2 HI(g) is at equilibrium at a fixed temperature with a partial pressure of H2 of atm, a partial pressure of I2 of atm, and a partial pres- sure of HI of atm. An additional atm pressure of HI is admitted to the con- tainer, and it is allowed to come to equilib- rium again. What is the new partial pressure of HI?
