Obr.8.3:Change in the extent of reaction with pressure for the formation of dinitrogen tetraoxide.
- If the reaction is endothermic, both the equilibrium constant and the equilibrium
extent of the reactionincreasewith increasing temperature.
8.5.4 Effect of inert component
The wordinertis used for all components in a mixture which do not participate in a given
reaction. These components dilute the reaction mixture. Let us consider only homogeneous
system in this subsection.
- If the reaction proceeds without any change in the total amount of substances (∆ν= 0),
the inerthas no effecton the equilibrium extent of the reaction. - If the reaction proceeds with an increasing total amount of substances (∆ν(g)> 0), the
equilibrium extent of the reactionincreaseswith increasing concentration of the inert. - If the reaction proceeds with an deceasing total amount of substances (∆ν(g)< 0), the,
the equilibrium extent of the reactiondecreaseswith increasing concentration of the
inert.
