The following reactions have the same frequency factor (A) and are performed at the same temperature.
Reaction A. Ea = 10 kJ/mol; ΔE = −30 kJ/mol
Reaction B. Ea = 50 kJ/mol; ΔE = +25 kJ/mol
Reaction C. Ea = 20 kJ/mol; ΔE = −40 kJ/mol
Determine which reaction is the slowest and which is the fastest.
