The water-gas shift reaction co(g)+h2o(g)⇌co2(g)+h2(g) is used industrially to produce hydrogen. the reaction enthalpy is δh∘=−41kj. to increase the equilibrium yield of hydrogen would you use high or low temperature?

Equilibrium yield of hydrogen will increase at lower temperature.

Explanation:

Change in standard enthalpy change () for water-gas shift reaction is negative.That means the given reaction is exothermic. So heat is produced in formation of Hence decrease in temperature would lead to shift of equilibrium towards forward direction i.e. formation of and to satisfy Le-chatelier principle.So, equilibrium yield of hydrogen will increase at lower temperature.

The answer for this question is d. none of these
