Why reaction orders greater than 1 reactions conversion more

In summary, reactions with orders greater than 1 have a higher conversion rate because they involve multiple reactant molecules colliding with each other simultaneously. This increases the chances of successful collisions and therefore increases the rate of reaction. The reaction order directly affects the rate of conversion, with a higher reaction order resulting in a faster conversion rate. However, a reaction with a low order can still have a high conversion rate if it has a high concentration of reactants or a high activation energy. The reaction order is directly related to the rate law, with the reaction order being the exponent in the rate law equation that determines how the concentration of reactants affects the rate of reaction. The reaction order is a constant value that does not change during the course of a

Welcome to the PF.

Can you provide a link to that statement? Is it a translation, or was the original text in English?

Can you write the mass balance to show the reaction rate as a function of concentration for a second order reaction?
 

1. Why do reactions with orders greater than 1 have a higher conversion rate?

Reactions with orders greater than 1 have a higher conversion rate because they involve multiple reactant molecules colliding with each other simultaneously. This increases the chances of successful collisions and therefore increases the rate of reaction.

2. How does the reaction order affect the rate of conversion?

The reaction order directly affects the rate of conversion. A higher reaction order means that the rate of reaction is more dependent on the concentration of the reactants, resulting in a faster conversion rate.

3. Can a reaction with a low order still have a high conversion rate?

Yes, a reaction with a low order can still have a high conversion rate. This can occur if the reaction has a high concentration of reactants or if the reaction has a high activation energy, meaning it requires a lot of energy to occur.

4. How does the reaction order relate to the rate law?

The reaction order is directly related to the rate law. The rate law is an equation that describes the relationship between the concentration of reactants and the rate of reaction. The reaction order is the exponent in the rate law equation that determines how the concentration of the reactants affects the rate of reaction.

5. Can the reaction order change during the course of a reaction?

No, the reaction order is a constant value for a specific reaction at a specific temperature. It does not change during the course of the reaction, but it can change if the temperature or concentration of reactants is altered.
