2HI(g)<>H2(g)+I2(g) The decomposition of HI(g) at 298k is represented by the equilibrium equation above. When 100 torr of HI(g) is added to a previously evacuated, rigid container and allowed to reach equilibrium the partial pressure I2(g) is approximately 3.7 torr. If the initial pressure of HI(g) is increased to 200 torr. And the process is repeated at the same temperature, which of the following correctly predicts the equilibrium partial pressure of I2(g). And why?
A) PI2 = 14, torr because it is directly proportional to the square of the initial pressure of HI
B) PI2=.073 torr because it is inversely proportional to the square of the initial pressure of HI
C) PI2=7.4 torr because it is directly proportionate to the initial pressure of HI
D) PI2=1.9 torr because it is inversely proportional to the initial pressure of HI
