The rate of a reaction typically increases as the temperature increases because ________.
A) the A term in the Arrhenius equation increases
B) the fraction of molecules with kinetic energy greater than Ea increases
C) the activation energy decreases
D) the activation energy increases
E) the molecules make more collisions with the wall of the reaction vessel
Activation Energy
The minimum amount of energy required to initiate a chemical reaction, determining the reaction rate.
Arrhenius Equation
A formula that gives the rate of a reaction as a function of temperature, providing a basis for understanding temperature effects on reaction rate constants.
- Relate reaction conditions, such as temperature and concentration, to the rate of reaction.

Final Answer :
B
Explanation :
Increasing the temperature leads to an increase in the kinetic energy of molecules, and according to the Boltzmann distribution, the fraction of molecules with energy greater than the activation energy increases, making more collisions successful and leading to a higher reaction rate.
