Question
H2 + I2 <---> 2HIKp=100
Initially, a flask contains hydrogen gas at 0.010atm iodine gas at 0.0050atm, and hydorgen iodide gas at 0.50atm. Determine equilibrium partial pressure of each gas in the flask. H2 + I2 <---> 2HI
Kp=100
Initially, a flask contains hydrogen gas at 0.010atm iodine gas at 0.0050atm, and hydorgen iodide gas at 0.50atm. Determine equilibrium partial pressure of each gas in the flask.
Kp=100
Initially, a flask contains hydrogen gas at 0.010atm iodine gas at 0.0050atm, and hydorgen iodide gas at 0.50atm. Determine equilibrium partial pressure of each gas in the flask.
Explanation / Answer
H2 + I2 <----------> 2 HI
0.01 0.005 0.50
0.01-x 0.005 -x 0.50 + 2x
Kp = P2HI / PH2 x PI2
100 = (0.50 - 2x)^2 / (0.01-x)(0.005-x)
x = - 0.03548
equilibrium partial pressures ;
PH2 = 0.0455 atm
PI2 = 0.0405 atm
PHI = 0.184 atm
