NEET Chemistry Activation Energy MCQ Question
Which of the following statements about activation energy is correct?
Activation energy is a constant specific to a particular reaction and is measured in joules/mole.
A higher activation energy always results in a faster reaction rate at constant temperature.
The Arrhenius factor is unrelated to activation energy and has no impact on the reaction rate.
Activation energy can be decreased by increasing the concentration of reactants.
Correct Answer
Detailed Explanation
Activation energy (Ea) is indeed a constant specific to a reaction, measured in joules/mole, as stated in the NCERT context. Higher activation energy does not necessarily lead to faster reaction rates, and the Arrhenius factor is intrinsically linked to activation energy in the Arrhenius equation.
