Energy required to form transition state is called _________________?
Correct answer: A. Ea
- A. Ea
- B. P.E
- C. V
- D. K.E
Explanation
Activation energy, Ea, is the minimum energy required for reactants to reach the transition state or activated complex. Students may choose potential energy because the transition state lies at a high point on a potential-energy diagram, but the energy difference required to reach it is specifically called activation energy.

About Activation Energy and Activated Complex
Activation energy is the minimum energy reactant particles need to form the activated complex, or transition state, during a reaction. Energy profile diagrams show the forward and reverse activation energies, while catalysts provide an alternative pathway with lower activation energy without changing the reaction enthalpy.
