Consider the reaction : 2SO2 + O2 ............. 2SO3 + Heat will be maximum if :

Explanation

The reaction 2SO2 + O2 → 2SO3 is exothermic, releasing heat. According to Le Chatelier's principle, increasing pressure shifts the equilibrium towards the side with fewer moles of gas, which is the forward reaction. Increasing temperature enhances the reaction rate by providing more energy to overcome activation energy. Therefore, the reaction rate and product formation are maximized when both pressure and temperature are increased.Options A and C, although they involve increasing pressure, do not involve increasing temperature, which is necessary to maximize the reaction rate. Option B decreases both pressure and temperature, which is counterproductive to both reaction rate and product formation.
