Question

What are the factors affecting the rate of chemical reaction?

Hint:

The rate of a chemical reaction depends on multiple factors. Temperature is one of the most important—higher temperatures increase particle movement, leading to faster reactions.

Answer 1

Step 1: Understanding reaction rate
The rate of a chemical reaction refers to how quickly reactants are converted into products. Various factors influence the reaction speed. 
Step 2: Explanation of factors 
- Concentration: Higher reactant concentration increases the rate due to more frequent collisions. 
- Temperature: Raising temperature increases particle movement, leading to more effective collisions. 
- Surface area: Smaller particle size exposes more surface area, increasing the reaction rate. 
- Catalyst: A catalyst speeds up a reaction without being consumed. 
- Pressure: In gaseous reactions, higher pressure increases the reaction rate. 
- Nature of reactants: Some substances react faster due to their chemical properties. 
- Light: Some reactions, like photosynthesis, require light energy.
