Question

On increasing the temperature by 10 K the rate of reaction becomes double. Which of the following is the most appropriate reason? (A) With increase of temperature, velocities increase and hence the numberofcollisions is appreciably increased. (B) The activation energy decreases with increase of temperature. (C) The bonds between the atoms of the reacting molecules become weak at higher temperature. (D) Higher the temperature, larger is the fraction of colliding particles which can cross the energy barrier.

The activation energy decreases with increase of temperature.

The bonds between the atoms of the reacting molecules become weak at higher temperature.

Higher the temperature, larger is the fraction of colliding particles which can cross the energy barrier.
