For an endothermic reaction, which of the following is true:
a. the activation energy of the forward reaction is greater than that of the reverse reaction.
b. the forward and reverse reactions are equal in terms of their energy requirements.
c. the reverse reaction releases less energy than the forward reaction.
d. if the temperature decreases, the forward reaction will stop.

I had originally thought that the correct answer was a., but then d. caught my eye and now I am not entirely sure. Which is actually correct?

product has more energy than the reactants.

does the forward reaction (in an endothermic reaction) actually "stop" when the temperature decreases? I know that decreasing heat in an endothermic reaction will shift the equilibrium to the left in favor of reactants, but would that cause the forward reaction to actually "stop"?
