Thus, u (rate) ∞ T
Hence, rate increases with increase in temperature.
Distribution of molecules (N) with velocity (u) at two temperatures is shown as
When temperature is increased, fraction of molecules with energy excess of Ea is increased.
Thus, both Statements I and II are correct and Statement II is the correct explanation of Statement I.

Statement I: The rate of chemical reaction generally increases rapidly for a small temperature increase.
Statement II: Increase in temperature increases fraction of molecules with energies in excess of activation energy.
The correct answer is option A: Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.
Explanation:
Statement I: The rate of chemical reaction generally increases rapidly for a small temperature increase.
When the temperature of a system increases, the kinetic energy of the molecules also increases. This increased kinetic energy leads to an increase in the frequency of collisions between reactant molecules. According to the collision theory, an increase in the frequency of collisions increases the rate of the chemical reaction. Therefore, Statement I is correct.
Statement II: Increase in temperature increases fraction of molecules with energies in excess of activation energy.
The activation energy is the minimum amount of energy required for a chemical reaction to occur. At any given temperature, only a fraction of the reactant molecules possess energies greater than the activation energy. This fraction of molecules is responsible for successful collisions leading to a chemical reaction.
When the temperature is increased, the kinetic energy of the molecules increases. This higher kinetic energy means that a greater fraction of molecules will have energies in excess of the activation energy. Therefore, an increase in temperature increases the fraction of molecules that can undergo successful collisions and participate in the chemical reaction.
Therefore, Statement II is also correct, and it provides a correct explanation for Statement I.
In conclusion, both Statement I and Statement II are correct, and Statement II provides a correct explanation for Statement I.
Statement II: Increase in temperature increases fraction of molecules with energies in excess of activation energy.
The correct answer is option A: Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.
Explanation:
Statement I: The rate of chemical reaction generally increases rapidly for a small temperature increase.
When the temperature of a system increases, the kinetic energy of the molecules also increases. This increased kinetic energy leads to an increase in the frequency of collisions between reactant molecules. According to the collision theory, an increase in the frequency of collisions increases the rate of the chemical reaction. Therefore, Statement I is correct.
Statement II: Increase in temperature increases fraction of molecules with energies in excess of activation energy.
The activation energy is the minimum amount of energy required for a chemical reaction to occur. At any given temperature, only a fraction of the reactant molecules possess energies greater than the activation energy. This fraction of molecules is responsible for successful collisions leading to a chemical reaction.
When the temperature is increased, the kinetic energy of the molecules increases. This higher kinetic energy means that a greater fraction of molecules will have energies in excess of the activation energy. Therefore, an increase in temperature increases the fraction of molecules that can undergo successful collisions and participate in the chemical reaction.
Therefore, Statement II is also correct, and it provides a correct explanation for Statement I.
In conclusion, both Statement I and Statement II are correct, and Statement II provides a correct explanation for Statement I.
