Methanol is synthesized by the gas phase reaction: Stoichiometric amounts of CO and H2 are mixed in an evacuated vessel (i.e. no methanol is present initially), and the reaction is allowed to come to equilibrium. Calculate the equilibrium mole fraction of methanol under the following conditions.

CO+2H2-> CH3OH

(c) The equilibrium temperature and pressure are 365 K and 1 atm, the mixture behaves as an ideal gas and a more accurate description of the temperature dependence of the equilibrium constant is available where T is in K. ln K = 21.8158+9,052/(T)-7.663ln(T)+5.4075x10-3 (T)-5.75x10-7 (T2 )-6.75x103 /(T2 )
