Problem

Two independent reactions have the following energy characteristics: • Reaction A: Ea=150 kJ mol−1E_a = 150\,\text{kJ mol}^{-1}, ΔG∘=−80 kJ mol−1\Delta G^\circ = -80\,\text{kJ mol}^{-1} • Reaction B: Ea=40 kJ mol−1E_a = 40\,\text{kJ mol}^{-1}, ΔG∘=−10 kJ mol−1\Delta G^\circ = -10\,\text{kJ mol}^{-1} At room temperature, which reaction is more likely to be classified as kinetically controlled? Justify your choice in one sentence.
