The water–gas shift reaction is important in several chemical processes, such as the production of H2 for fuel cells. This reaction can be written as follows:
H2(g)+CO2(g) ↔H2O(g)+CO(g)
K=0.106 K at 700 K. If a mixture of gases that initially contains 0.0150 M H2and 0.0150 M CO2is allowed to equilibrate at 700 K, what are the final concentrations of all substances present? (Ans [H2]f = 0.0113M, [CO2]f = 0.0113M, [H2O]f = 0.00369M, [CO]f = 0.00369M)
