What is the Difference Between Catalytic and Non Catalytic Reaction?
🆚 Go to Comparative Table 🆚The main difference between catalytic and non-catalytic reactions lies in the presence or absence of a catalyst. A catalyst is a substance that accelerates a chemical reaction by decreasing its activation energy. Here are the key differences between the two types of reactions:
- Catalytic Reactions:
- Involve a catalyst that increases the rate of reaction.
- Can be either homogeneous (catalyst and reactants are in the same phase) or heterogeneous (catalyst and reactants are in different phases).
- Generally occur more quickly than non-catalytic reactions due to the lowering of activation energy.
- Non-catalytic Reactions:
- Do not involve a catalyst, and the reaction rate is not increased by any external influence.
- Can be classified into homogeneous (reactants and products are in the same phase) or heterogeneous (reactants and products are in different phases) reactions.
- Typically occur more slowly than catalytic reactions because the activation energy is not lowered.
In summary, catalytic reactions involve a catalyst that speeds up the reaction, while non-catalytic reactions do not have a catalyst and proceed at a slower rate. Catalytic reactions can be further classified into homogeneous or heterogeneous reactions, depending on the phase of the catalyst and reactants.
Comparative Table: Catalytic vs Non Catalytic Reaction
Here is a table comparing catalytic and non-catalytic reactions:
| Catalytic Reactions | Non-Catalytic Reactions |
|---|---|
| Involve a catalyst that increases the reaction rate | Do not involve a catalyst, and the reaction rate is not increased by any external influence |
| Catalyst is never consumed during the reaction, making it available for reuse | No catalyst is present to help reduce the activation energy, making the reaction rate slower |
| Can be homogeneous (catalyst in the same phase as reactants) or heterogeneous (catalyst in a different phase from reactants) | Reactants and products are in the same phase (homogeneous) or different phases (heterogeneous) |
| Lower the activation energy for both the forward and reverse reactions, allowing the system to reach equilibrium more quickly | Do not lower the activation energy, making it more difficult for the system to reach equilibrium |
| Examples of catalytic reactions include enzyme-catalyzed reactions and heterogeneous catalysis in catalytic converters | Examples of non-catalytic reactions include chemical reactions that do not involve a catalyst and rely solely on the reactants and their properties |
In summary, catalytic reactions involve a catalyst that increases the rate of the reaction by reducing the activation energy, while non-catalytic reactions do not have a catalyst and rely solely on the properties of the reactants to determine the reaction rate.
