Temperature Dependance of WGS 100E+05 3) Sketch a potential energy diagram for the water-gas shift reaction H2O + CO + H2 + CO2 given that it is exothermic (-41.2 kJ/mole) in the forward direction (at 298 K) and indicate the activation energies for both the forward and reverse reactions. a) What would be the effects of (i) increasing temperature and (ii) pressure upon the equilibrium position of the reaction? b) Given the equilibrium constant for the reaction approaches a value of 1 at 1100 K, what does this say regarding reaction kinetics or thermodynamics? (be quantitative in your answer). c) Illustrate on the same potential energy diagram how a catalyst would alter the activation energy. 1.00E+04 1.00E+03 1.00E+02 1.00E+01 1.00E-00 1.00E-01 300 500 700 1100 1300 1500 900 Temperature (K)
