A reaction mixture is said to be "under kinetic control" at 298 K. Which of the following best describes the situation?
a) ΔG∘<0 and the reaction proceeds rapidly at 298\,\text{K}.
b) ΔG∘>0 and the reaction rate is negligible because the activation energy is large.
c) ΔG∘<0 but the reaction rate is negligible because the activation energy is large.
d) The system has reached equilibrium, so no further net reaction is observed.
