II. Increased numbers of molecules possess energy greater than the activation energy
III. Decreased randomness of the system

Solution
The correct option is C I and II only
Option C is the correct answer.On increasing the Temperature of the gas, the random movement of the molecules of the gas also increases and hence the frequency of collision among the molecules also increases.Activation energy of the gas molecules also depends on the temperature of the gas. On increasing the temperature, the number of molecules possessing energy greater than the activation energy will also increase.
Option C is the correct answer.
On increasing the Temperature of the gas, the random movement of the molecules of the gas also increases and hence the frequency of collision among the molecules also increases.
Activation energy of the gas molecules also depends on the temperature of the gas. On increasing the temperature, the number of molecules possessing energy greater than the activation energy will also increase.
