For a solid-catalyzed gas-phase reversible reaction, which statement is ALWAYS true?
- AAdsorption is rate-limiting
- BDesorption is rate-limiting
- Solid catalyst does not affect equilibrium conversion
- DTemperature does not affect equilibrium conversion
Explanation
A catalyst changes only the rate (pathway), not the equilibrium position, which is fixed by thermodynamics — this is always true regardless of catalyst.
