The most important commercial process for generating hydrogen gas is the water-gas shift reaction: CH4(g) + H2O(g) ? CO(g) + 3H2(g) a)Use tabulated thermodynamic data to find?G° for this reaction at the standard temperature of 25°C. the answer to this one is 1.423*10^2 kJ b) Now calculate ?G°1250 for this process when it occurs at 1250 K.
When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag
