3 $$\times$$ 10^-1 mol L^-1

3 $$\times$$ 10^-3 mol L^-1

3 $$\times$$ 10³ mol L^-1

3.3 $$\times$$ 10² mol L^-1

Consider the reaction equilibrium
2 SO₂ (g) + O₂ (g) $$\leftrightharpoons$$ 2 SO₃ (g); $$\Delta H^o$$ = -198 kJ
One the basis of Le Chatelier's principle, the condition favourable for the forward reaction is :

increasing temperature as well as pressure

lowering the temperature and increasing the pressure

any value of temperature and pressure

lowering temperature as well as pressure
