At temperature near 800°c, steam passed over hot coke (a form of carbon obtained from coal) reacts to form co and h2: c(s) + h2o(g) ↔ co(g) + h2(g) the mixture of gases that results is an important industrial fuel called water gas.
a) at 800°c the equilibrium constant for this reaction is kp = 14.1. what are the equilibrium partial pressures of h2o, co, and h2 in the equilibrium mixture at this temperature if we start with solid carbon and 0.100 mol of h2o in a 1.00 l vessel?
b) what is the minimum amount of carbon required to achieve equilibrium under these conditions?
c) what is the total pressure in the vessel at equilibrium?
d) at 25°c the value of kp for this reaction is 1.7∙10-21. is the reaction exothermic or endothermic?
e) to produce the maximum amount of co and h2 at equilibrium should the pressure of the system be increased or decreased?
