EQUILIBRIUM FOR CHEMISTRY

The system

H2(g) + I2(g) ⇀↽ 2 HI(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 0.24

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?

Answer in units of atm.
