How is the composition of equilibrium mixture affected by:

(i) a change in temperature
(ii) a change in pressure
(iii) a change in concentration of N₂O₄
(iv) the removal of NO₂ from the reaction mixture

Correct the following statements :   

The enthalpy of a system is an intensive property i.e. its value depends on the amount of matter in the system.
