For an endothermic reaction, where All represents the enthalpv of the reaction in kJ/mot, the minimum value for the energy of activation will be:
Correct answer: C. Mole than ∆H
- A. Less than ∆H
- B. Zero
- C. Mole than ∆H
- D. Equal to ∆H
Explanation
Non spontaneous processes are endothermic process.few examples are:(i) Pumping of water uphill(ii) Transfer of heat from cold interior part nof the refrigerator to the hot surroundings.s process is the reverse of the spontaneous process. It does not take place on its own and does not occur in nature. Reversible processes constitute a limiting case between spontaneous and non-spontaneous processes. Some non-spontaneous processes, can be made to take place by supplying energy to the system from external source. Some examples of non- spontaneous processes are given below.Transfer of heat from cold interior part nof the refrigerator to the hot suron-spontaneous process is the reverse of the spontaneous process.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
