When it comes to gaseous substances, the concentration can be expressed as either a molarity value or a partial pressure value. The partial pressure for a gas can be determined using PV = nRT. (R = Gas law constant). When solving an equilibrium using a Kp value you must use the partial pressures of the gases rather than the molarity. Complete the following problem using your knowledge of equilibrium and partial pressures. The reaction of H2(g) and I2(g) to give HI(g) has an equilibrium constant, Ke, of 56 at 435°C.

When it comes to gaseous substances, the concentration can be expressed as either a molarity value or
a partial pressure value. The partial pressure for a gas can be determined using PV = nRT. (R = Gas law
constant). When solving an equilibrium using a Kp value you must use the partial pressures of the gases
rather than the molarity. Complete the following problem using your knowledge of equilibrium and
partial pressures.
The reaction of H2(g) and I2(g) to give HI(g) has an equilibrium constant, Ko, of 56 at 435°C.
H2(g) + I2(g) = 2HI(g)
A chemist mixes 0.45 mol of H2 and 0.45 mol of I2 in a 10.0 L flask at 435°C and allows the
