Explanation:
Catalyst
- A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.
- It works by providing an alternative reaction pathway with a lower activation energy.
Effect on Free Energy Change
- A catalyst does not affect the overall free energy change of a reaction.
- It does not change the difference in energy between the reactants and products.
- Therefore, the free energy change remains the same with or without a catalyst.
Role of Catalyst
- The presence of a catalyst can lower the activation energy required for the reaction to occur.
- This allows the reaction to proceed faster by providing an alternate mechanism with a lower energy barrier.
- As a result, the reaction reaches equilibrium faster, but the equilibrium position and free energy change remain unchanged.
Conclusion
- In summary, a catalyst neither increases nor decreases the free energy change of a reaction.
- It only affects the rate of the reaction by lowering the activation energy required for the reaction to proceed.
- Therefore, the nature of the catalyst does not impact the overall free energy change of the reaction.
