Which outcome arises when a nickel catalyst deactivates during ethene hydrogenation?

💡 Explanation

Deactivation increases the activation energy requirements because catalyst poisoning hinders reactant adsorption via active site coverage. Therefore, a higher energy input is needed, rather than altered equilibrium or reaction heat effects that would arise from different mechanisms.
