Class 11Chemistry1 Equilibrium: Chemical EquilibriumMix Examples- 6-1.Equilibrium (Chemical Equilibrium)
MediumState the important biological and environmental chemical equilibrium with examples.
(N/A) Chemical equilibria are essential in numerous biological and environmental processes.
$1$. Biological Equilibrium: The equilibrium involving $O_2$ molecules and the protein hemoglobin $(Hb)$ plays a crucial role in the transport and delivery of $O_2$ from our lungs to our muscles.
$Hb(aq) + 4O_2(g) \rightleftharpoons Hb(O_2)_4(aq)$
$2$. Environmental Equilibrium: The biochemical equilibrium between $CO$ molecules and hemoglobin is significant.
$Hb(aq) + 4CO(g) \rightleftharpoons Hb(CO)_4(aq)$
This equilibrium accounts for the toxicity of $CO$,as $CO$ binds more strongly to hemoglobin than $O_2$ does.
Key characteristics of equilibrium:
- At equilibrium,the properties of the mixture remain constant.
- Equilibrium can be attained from either the forward or reverse direction.
- Equilibrium is dynamic in nature.
- External factors like temperature,pressure,and concentration affect the position of equilibrium.

View SolutionConsider the reaction,$P(aq) \rightleftharpoons Q(aq)$ with an equilibrium constant $K=1.5$. The reaction is started in a vessel with a concentration of $[P]$ of $2 \ M$ and concentration of $[Q]=0$. When the equilibrium is established,half the amount of $P$ is removed,and the reaction is allowed to re-equilibrate. The concentration of $Q$ in the vessel (in $M$) is closest to
