Consider the following statements and select the correct code.
Assertion (A): A chemical reaction becomes faster at higher temperature.
Reason (R): At higher temperature, molecular motion becomes more rapid.
  • a)
    Both A and R are true and R is the correct explanation of A.
  • b)
    Both A and R are true, but R is not correct explanation of A.
  • c)
    A is true, but R is false.
  • d)
    A is false, but R is true.
Correct answer is option 'A'. Can you explain this answer?

The rates of most reactions increase with a rise in temperature. Raising the temperature increases the fraction of molecules having very high kinetic energies. These are the ones most likely to react when they collide. The higher the temperature, the larger the fraction of molecules that can provide the activation energy needed for reaction.

Explanation:

  • The assertion (A) is true because at higher temperature, the kinetic energy of the reactant molecules increases, and they move faster, leading to more frequent and energetic collisions between reactant molecules, thus increasing the rate of the reaction.

  • The reason (R) is also true because at higher temperature, the molecular motion becomes more rapid due to the increase in kinetic energy of the molecules, which leads to more frequent collisions between the reactant molecules.

  • Moreover, the increase in temperature also increases the number of molecules with sufficient energy to overcome the activation energy barrier required for the reaction to take place.

  • Therefore, the correct code is (A) where both the assertion and the reason are true, and the reason correctly explains why the assertion is true.
