step 1 Dear students, in problem 28 of chapter 5, we have asked that the following reactions are known

The following reactions are known to occur in the body...

The following reactions are known to occur in the body $\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \leftrightarrow \mathrm{H}_{2} \mathrm{CO}_{3} \leftrightarrow \mathrm{H}^{+}+\mathrm{HCO}_{3}^{-1}$ If $\mathrm{CO}_{2}$ escapes from the system a. $\mathrm{pH}$ will decrease b. Hydrogen ion concentration will diminish c. $\mathrm{H}_{2} \mathrm{CO}_{3}$ concentration will remain unchanged d. the forward reaction will be favoured.

Key Concepts

Chemical Equilibrium

Chemical equilibrium refers to the state in a reversible reaction where the forward and reverse reaction rates are equal, resulting in constant concentrations of reactants and products. This concept is fundamental in understanding how changes in concentration, temperature, or pressure can shift the position of the equilibrium, influencing the outcome of the reaction and the concentrations of the species involved.

Le Chatelier's Principle

Le Chatelier's Principle states that when an external change is imposed on a system at equilibrium, the system will adjust itself to counteract that change and reestablish equilibrium. In the context of removing CO? from the system, this principle predicts that the equilibrium will shift in the direction that produces more CO?, affecting the concentrations of other species in the reaction.

Buffer Systems in Physiology

Buffer systems in physiology, such as the CO?/H?CO?/HCO?? system, are critical for maintaining stable pH levels in the body. These systems work by neutralizing added acids or bases to minimize pH fluctuations. Understanding how the removal or addition of a component like CO? impacts the equilibrium is key to comprehending how the body regulates its pH balance.
