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 ΔG° for this
reaction at the standard temperature of 25°C.
b) Now calculate ΔG°1100 for this process when it
occurs at 1100 K.
What percentage of resulted Hydrogen in the reaction: CH4 (g) + NH3 (g) --> HCN (g)...
What percentage of resulted Hydrogen in the reaction:
CH4 (g) + NH3 (g) --> HCN (g) + 3H2 (g) must be burnt, with
formation if H2O (g), to ensure the quantity of heat absorbed in
the reaction?
(the answer is: approximately 35%)
Heat of formation : Hf (kJ/mol)
CH4 (g) = -74,7
NH3 (g) = -46,2
HCN (g) = 130,5
H2O (g) = -241,6

Hydrogen gas (a potential future fuel) can be formed by the
reaction of methane with water according to the following equation:
CH4(g)+H2O(g)→CO(g)+3H2(g)CH4(g)+H2O(g)→CO(g)+3H2(g) In a
particular reaction, 26.5 LL of methane gas (measured at a pressure
of 736 torr and a temperature of 25 ∘C) is mixed with 22.6 L of
water vapor (measured at a pressure of 702 torr and a temperature
of 125 ∘C). The reaction produces 26.2 L of hydrogen gas at STP.
