Increasing the temperature gives the molecules more kinetic energy. Hence, option D is correct.
What is the rate of a reaction?
The rate of a reaction is the speed at which a chemical reaction takes place.
Temperature is also known as the average kinetic energy of molecules.
Some atoms used to have sufficient kinetic energy to react, while others do not.
Increasing the temperature indicates that more numbers of molecules will have sufficient kinetic energy to react and reactions will take place more frequently.
Hence, increasing temperature increases the reaction rate.
Thus, option D is correct.
