Problem

Three independent reactions have the following thermodynamic and kinetic data: • Reaction 1: Ea = 40 kJ mol⁻¹, ΔH = –50 kJ mol⁻¹ • Reaction 2: Ea = 25 kJ mol⁻¹, ΔH = –10 kJ mol⁻¹ • Reaction 3: Ea = 60 kJ mol⁻¹, ΔH = –100 kJ mol⁻¹ At 298 K, identify which reaction is kinetically favored and which is thermodynamically favored, and justify each choice in one sentence.
