Answer to Question #313742 in Organic Chemistry for swarnajeet kumar

Question

State Le- Chatelier’s principle and for the following reaction at equilibrium 2SO2(g) + O2(g) ⇌ 2SO3(g) ∆H = 198 kJ Predict the effect of i. Adding SO2(g) at equilibrium ii. Decreasing the temperature iii. Reducing the volume of the container to half iv. Adding an inert gas under conditions of constant pressure.

Answer 1

General statement of Le Chatelier's principle

It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.

(i) Equilibrium will shift in backward direction which means backward reaction will be favoured.

(ii) Equilibrium will shift in forward direction or more of SO3

​ will be formed.

(iii) Backward reaction will be favoured.

(iv) Backward reaction will be favoured.
