Several chemical processes utilize the water-gas shift reaction H20 () + CO (g) à H2 (g)...
The water-gas shift reaction CO(g)+H2O(g)?CO2(g)+H2(g) is used industrially to produce hydrogen. The reaction enthalpy is ?H?=?41kJ. Could you increase the equilibrium yield of hydrogen by controlling the pressure of this reaction? If so would high or low pressure favor formation of H2(g)?
Example: Water-Gas Shift Reaction (Felder and Rosseau, 2000) The water-gas shift reaction is another reaction also used to generate hydrogen in large industrial plants: CO + H20 CO2 + H2 The equilibrium constant at 1105 K is 1.00. If you feed the reactor with 1 mol of Co, 2 mol of H20, what will be the chemical composition at equilibrium?
The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal: CO(g)+H2O(g) CO2(g)+H2(g) A Study was made in which equilibrium was reached with [CO]=[H2]=[H2O]=.100 M and [CO2]=.400 M. After .300 mol of H2 is added to the 2-L container ad equilibrium is reestblished, what are the new concentrations of ALL of the components?
For the extremely important '"water gas shift" reaction shown below, the Kc= 6.74 x 10^-2 at a certain temperature. What are the equilibrium concentrations of all the components of the reaction if 0.742 moles of CO and H20 are initially mixed with 0.399 moles of CO2 and 0.941 moles of H2 in a 2.5L flask?

Select the best single answer. The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal: CO(g) + H2O(g) ⇌ CO2(g) + H2(g) At a given temperature, Kp = 2.7. If 0.13 mol of CO, 0.56 mol of H2O, 0.62 mol of CO2, and 0.47 mol of H2 are put in a 2.0−L flask, in which direction does the reaction proceed? The reaction will proceed to the right OR the reaction is at...

The H2/CO ratio in mixtures of carbon monoxide and hydrogen (called synthesis gas) is increased by the water-gas shift reaction CO(g)+H2O(g)⇌CO2(g)+H2(g), which has an equilibrium constant Kc=4.24 at 800 K. Part A Calculate the equilibrium concentrations of CO2, H2, CO, and H2O at 800 K if only CO and H2O are present initially at concentrations of 0.132 M .
