4.66. Methanol is formed from carbon monoxide and hydrogen in the gas-phase reaction CO 2H2 CH3OH (A) (B) (C) The mole fractions of the reactive species at equilibrium satisfy the relation 1 = Ke(T where P is the total pressure (atm), Ke the reaction equilibrium constant (atm2), and T the temperature (K). The equilibrium constant Ke equals 10.5 at 373 K, and 2.316 x 10-4 at 573 K. A semilog plot of Ke (logarithmic scale) versus 1/T (rectangular scale) is...

Hydrogen and carbon dioxide can be used to produce carbon monoxide according to the water-gas shift reaction given by: H2 + CO2 = CO + H2O. If a reaction is set-up initially with n moles each of H2 and CO2 and none of either of the products, CO and H2O, and the variable x represents the fraction of H2 dissociated at equilibrium. Complete the following table in terms of n and x. H2 CO2 CO H2O Total moles Moles at...
The synthesis of methanol from carbon monoxide and hydrogen gas is described by the following chemical equation: CO(g)+2H2(g)⇌CH3OH(g)CO(g)+2H2(g)⇌CH3OH(g) The equilibrium constant for this reaction at 25 ∘C∘C is Kc=2.3×104Kc=2.3×104. In this tutorial, you will use the equilibrium-constant expression to find the concentration of methanol at equilibrium, given the concentration of the reactants. 1. a. Suppose that the molar concentrations for COCO and H2H2 at equilibrium are [CO][CO] = 0.04 MM and [H2][H2] = 0.04 MM. Use the formula you found...

"Synthesis gas" is a mixture of carbon monoxide and water vapor. At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially. A chemical engineer studying this reaction fills a 500. mL flask at 20·°C with 4.9 atm of carbon monoxide gas and 2.5 atm of water vapor. He then raises the temperature considerably, and when the mixture has come to equilibrium determines that it contains...
