The system

H2(g) + I2(g) ⇌ 2HI(g

) is at equilibrium at a fixed temperature with a partial pressure of H2 of 0.200 atm, a partial pressure of I2 of 0.200 atm, and a partial pressure of HI of 0.100 atm. An additional 0.26 atm pressure of HI is admitted to the container, and it is allowed to come to equilibrium again. What is the new partial pressure of HI?

A.0.360 atm

B. 0.464 atm

C. 0.152 atm

D. 0.104 atm

An equilibrium mixture for the following reaction: H2(g) + I2(g) <---> 2HI(g) is composed of the following: P(I2) = 0.08592 atm; P(H2) = 0.08592 atm; P(HI) = 0.5996 atm. If this equilibrium is disturbed by adding more HI so that the partial pressure of HI is suddenly increased to 1.0000 atm, what will the partial pressures of each of the gases be when the system returns to equilibrium?
