Which outcome regarding hydrogen consumption results when a water-gas shift reactor's equilibrium constant (K) drastically decreases?

💡 Explanation

A decreased K implies the reverse reaction (CO2 + H2 ⇌ CO + H2O ) is more favorable, because a lower equilibrium constant means a lower ratio of products to reactants. The reverse rate increases, therefore more hydrogen is produced, rather than being consumed by driving the forward reaction.
