Factors affecting rate if reaction

1. Surface area

1.1. larger the no of surface area, larger collision ,greater rate of reaction

2. Catalyst

2.1. Positive catalys increases the rate of reaction by decreasing the activation energy

2.2. Negative catalyst decrease rate of reaction by increasing the activation energy

3. Nature of reactants

3.1. reactions involving bond rearrangements have higher activation energy and slower in reaction whereas reaction which doesn't involve rearrangement of bond are faster in nature.

4. Higher the temperature, greater the collision, greater rate of reaction

5. Temperature

6. Concentration

6.1. Greater the concentration of reactants, larger the collision , greater the rate of reaction
