Consider the reaction N₂ ⇔ 2 N. Determine a numerical value for the equilibrium constant K_p for the reaction as written for temperatures of 500 K and 5000 K. Compare your results with Problem 13.19 and discuss.

Problem 13.19

In a steam reforming process, natural gas (or other hydrocarbon or coal) is used to produce hydrogen. In this process, the water–gas shift equilibrium reaction H₂O + CO ⇔ CO₂ + H₂ is important. Calculate the standard-state Gibbs function change for this reaction for temperatures of 1000 K, 1500 K, and 2000 K. Discuss the implications of your calculations.
