JEE MAIN - Chemistry (2003 - No. 8)
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 :
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

Due to exothermicity of reaction low or optimum temperature will be required. Since $$3$$ moles are changing to $$2$$ moles.
$$\therefore$$ High pressure will be required.
$$\therefore$$ High pressure will be required.
