Based on their activation energies and energy changes and assuming that all collision factors are the same, which of the following reactions would be fastest in the reverse direction?

	Ea= Ea3 = 53 kJ/mol , ΔE= ΔE3 = 8 kJ/mol .
	Ea= Ea2 = 35 kJ/mol , ΔE= ΔE2 = -10 kJ/mol .
	Ea= Ea1 = 43 kJ/mol , ΔE= ΔE1 = -27 kJ/mol .
	Ea= 35 kJ/mol , ΔE= ΔE2 = -10 kJ/mol and Ea= 53 kJ/mol , ΔE= ΔE3 = 8 kJ/mol .
