Catalytic Reaction Characteristics
Apr 17, 2018

Catalytic reactions have four basic characteristics that can be derived from the definition and are important for understanding the function of the catalyst.

1. The catalyst can only accelerate reactions that can be thermodynamically performed. When developing a new chemical reaction catalyst, it is first necessary to thermodynamically analyze the reaction to see if it is a thermodynamically feasible reaction.

2. The catalyst can only accelerate the reaction to equilibrium and cannot change the equilibrium position (equilibrium constant) of the reaction.

3. The catalyst is selective to the reaction. When the reaction may have more than one different direction, the catalyst accelerates only one of them, and the promotion of the reaction rate and selectivity is uniform.

4, the catalyst life. The catalyst can change the rate of the chemical reaction and does not enter the reaction itself. In the ideal case, the catalyst is not changed by the reaction. However, in the actual reaction process, long-term thermal and chemical reactions of the catalyst can also occur some unpredictable physical and chemical changes.

According to the definition and characteristics of the catalyst, there are three important catalyst indicators: activity, selectivity, and stability.
