A mixture of 4.55atm of H2 and 4.55atm of I2 is contained in a 1.0L vessel at 430 degree C. The equilibrium constant (Kp) for the reaction: H2(g) + I2(g) <----> 2HI(g) at this temperature is 54.3. Determine the equilibrium partial pressures of H2, I2, and HI. PH2=_______atm PI2=______atm PHI=______atm
