Why does the rate of a reaction increase with rise in temperature?

Options

  1. AHigher temperatures increase the concentration of reactants.
  2. BAt higher temperatures, larger fraction of colliding particles can cross the energy barrier (i.e. the activati
  3. CHigher temperatures decrease the number of collisions between molecules.
  4. DHigher temperatures decrease the kinetic energy of reactant molecules.

Correct answer

B. At higher temperatures, larger fraction of colliding particles can cross the energy barrier (i.e. the activati

Step-by-step solution

Correct Option is : (B) At higher temperatures, larger fraction of colliding particles can cross the energy barrier (i.e. the activation energy), which leads to faster rate.
