Question

in most exergonic reactions, before products can be formed, the reactants must first overcome a thermodynamic barrier known as the...

○ entropy of the reaction.
○ energy conservation of the reaction.
○ chemical equilibrium of the reaction.
○ activation energy of the reaction

Explanation:

• Entropy is a measure of disorder, not a barrier.
• Energy conservation is a principle, not a barrier.
• Chemical equilibrium is a state, not a barrier.
• Activation energy is the minimum energy reactants need to overcome to form products.

Answer:

activation energy of the reaction.
