Question restatement: The prompt asks which reactions will have their equilibrium position shift when the container volume is changed. Option a: 'Only reactions where the number of moles of gas changes.' This is correct. According to Le Chatelier's principle, changing the volume affects the pressure of the system. A shift occurs only if the reaction involves a change in the number of gas moles (Δn_g ≠ 0). If the number of gas......Login to view full explanation
