Why do most chemical reaction rates increase rapidly as the temperature rises?
The correct answer to this question is option D: More collisions take place between particles so that the reaction can occur. This is known as the collision theory, which explains the relationship between temperature and reaction rates.
Collision Theory:
The collision theory states that for a chemical reaction to occur, particles must collide with each other in the correct orientation and with sufficient energy. When the temperature is increased, the kinetic energy of the particles also increases. This leads to several important factors that contribute to the increase in reaction rates.
Increased Frequency of Collisions:
As the temperature rises, the particles gain more kinetic energy and move faster. This increased speed leads to a higher frequency of collisions between particles.
Increased Energy of Collisions:
The increase in temperature also results in an increase in the average kinetic energy of the particles. This means that when particles collide, they are more likely to possess the necessary energy to overcome the activation energy barrier for the reaction to occur. Activation energy is the minimum energy required for a reaction to take place.
More Effective Collisions:
In addition to the increased frequency and energy of collisions, the higher temperature also leads to a greater proportion of particles having energies greater than the activation energy. This means that a larger fraction of collisions result in a successful reaction.
Conclusion:
Overall, as the temperature increases, the collision theory predicts that the rate of chemical reactions will increase. This is because the higher temperature leads to more frequent collisions, collisions with higher energy, and a greater fraction of collisions with sufficient energy to overcome the activation energy barrier. Therefore, option D is the correct answer.

As the temperature rises, more collisions start taking place which results in an increase in rate of the chemical reaction.
With rise in temperature, fraction of molecules possessing kinetic energy greater than the activation energy increases. Only such molecules are able to cause effective collisions and result in the formation of product. Thus, as the fraction of such molecules increases, rate of the reaction increases.
