Answer:
the correct answer is d (The activation energy of the reaction is large)
Explanation:
the Kp represents an equilibrium constant in terms of partial pressures. The fact that is less than 1 represents that the equilibrium favours reactants compared to products (the extent of the reaction) , but it does not speak about reaction rates.
If the ΔG of the reaction is positive then they would not be spontaneous , in contradiction with the problem's statement.
If the entropy change is negative or the reaction is endothermic , then it means that they contribute positively to the ΔG . But more positive ΔG does not necessarily means slower reaction rates
Nevertheless, the activation energy represents the energy barrier against the formation of products . When higher the activation energy , the reaction rates are slower. Thus the correct answer is d
Spontaneous reactions are actually very slow because
d. The activation energy of the reaction is large
What does Activation energy tells us?
The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.
The activation energy represents the energy barrier against the formation of products. Thus many spontaneous reactions are actually very slow because when higher the activation energy , the reaction rates are slower.
Thus, correct option is d.
