What are the factors which affects the rate of a chemical reaction. Explain ach of them by giving examples.
Answers
Answer:
Factors affecting reaction rate
Nature of reactants. Reaction rate variation is dependant on which substances are reacting. ...
Physical state. ...
Concentration. ...
Temperature. ...
Catalysts. ...
Pressure. ...
Stopped-flow. ...
Rapid kinetics fluorescence.
The factor that affect the rate of a chemical reaction are -
Concentration:
On increasing concentration of reactants, the probability of collisions of molecules increases hence rate of reaction increases.
Temperature :
On increasing the temperature , the kinetic energy of molecules increases , hence, the number of collision increases . Therefore , the rate of reaction also increases .
Pressure:
On increasing pressure , the molecules of gases come closer to each other. As a result their collisions increases and hence rate of reaction increases.
Surface Area of Reactants:
On increasing surface area reactants, the rate of reaction increases . For example , the powdered metals reacts faster than the metals in a lump .
Nature of reactants:
If the reactants are ionic in nature than the rate of reaction is faster than those in which reactants are molecular in nature .
