For a reaction, the threshold energy is 75 kJ/ mole. If the internal energy of the reactants is 20 kJ/ mole, the activation energy (in kJ/mole) is

Question

Accepted Answer

Correct answer: A. (a) Threshold energy = Activation energy + energy possessed by reacting species 75=E_a+20 or, E_a=75-20=55 kJ/ mol
