Chemistry - Chemical Kinetics Question with Solution | TestHub

Question Explanation: Identify the incorrect statement from the reaction coordinate diagram showing enthalpy. Concept: Reaction coordinate diagram (Enthalpy, Activation Enthalpy, Stability) Solution: 'C' is thermodynamically more stable as it has minimum Enthalpy value. 'D' is kinetically more stable as it requires lesser Ea compared to 'C'. Ea to form 'C' is ' 5 kJ more' than that of 'D' Final Answer: Activation enthalpy to form C is $5\mathrm{kJ}{\mathrm{mol}}^{-1}$ less than that to form D.
