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

💡 Solution & Explanation

Both statements are factually correct based on Le Chatelier's principle. If you remove some product, the system shifts forward to replace it, partially compensating for the loss (Statement II). However, the total moles at the new equilibrium will strictly be lower than the initial equilibrium because the forward shift only *partially* restores the lost moles. While Statement II is true, it is essentially a statement of Le Chatelier's principle rather than the mathematical derivation of why the total sum is less for this specific zero-order ($\Delta n = 0$) stoichiometry. Therefore, correct answer is B.
