Read the Assertion and Reason below and choose the correct option. — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

At equilibrium, the rates of the forward and backward reactions are exactly equal, meaning no net reaction occurs. Thus, a net reaction only occurs when a system is out of equilibrium (Statement I is true). Statement II is also a true thermodynamic principle (systems spontaneously move towards a minimum free energy equilibrium state). However, Statement II is not the direct explanation for Statement I, which is more of a kinetic definition. Therefore, correct answer is B.
