A pharmaceutical company wants to improve iodine starting from hydroiodic acid to produce gaseous iodine plus molecular hydrogen. 0.5 mol hydroiodic acid enters the reaction at a temperature of 200C and the volume of the reaction is 2 liters. When equilibrium is established, the moles of hydroiodic acid and iodine are equal.

Calculate:

a) The Ke and indicate where the equilibrium is directed

b) Kp
