Class 11Chemistry6-1.Equilibrium (Chemical Equilibrium)Mix Examples- 6-1.Equilibrium (Chemical Equilibrium)
MediumExplain the relationship between the time taken to reach equilibrium and thermodynamics.
(N/A) The equilibrium constant $K_{c}$ provides information about the ratio of products to reactants at equilibrium,but it does not indicate the rate of the reaction or the time required to reach equilibrium. Thermodynamics,specifically Gibbs free energy $(\Delta G)$,helps predict the spontaneity of a reaction.
$(i)$ If $\Delta G < 0$,the reaction is spontaneous and proceeds in the forward direction.
$(ii)$ If $\Delta G > 0$,the reaction is non-spontaneous in the forward direction.
$(iii)$ At equilibrium,$\Delta G = 0$. The time taken to reach this state is determined by the kinetics of the reaction,not by thermodynamics.
