The four (4) functions of water in the body are:

I. Site for many reactions.

II. Transport of nutrients and wastes.

III. Carries heat.

IV. Acts as solvent.

Water can be defined as a liquid molecule that comprises two (2) main chemical elements, which are hydrogen and oxygen in the ratio of two to one (2:1).

Generally, water is considered to be an important and essential chemical molecule that aids in the growth and development of the body of living organisms. The four (4) functions of water in the body of a living organism are:

  • It is typically a site for many reactions.
  • It helps in the transportation of nutrients and wastes around the body.
  • It carries heat from a hot region.
  • It acts as solvent to dissolve a solute to produce a solution.

What is the value of the equilibrium constant at 25 oC for the reaction between the pair: I2(s) and Br-(aq) Give your answer usi
insens350 [35]

Explanation:

Formula to calculate standard electrode potential is as follows.

          E^{o}_{cell} = E^{0}_{cathode} - E^{0}_{anode}

                             = 0.535 - 1.065

                             = - 0.53 V

Also, it is known that relation between E^{o}_{cell} and K is as follows.

            E^{o}_{cell} = \frac{RT}{nF} \times ln K

                 ln K = \frac{nFE^{0}_{cell}}{RT}      

Substituting the given values into the above formula as follows.

                 ln K = \frac{nFE^{0}_{cell}}{RT}    

                        =  \frac{2 \times 96485 C mol^{-1} \times -0.53 V}{8.314 l atm/mol K \times 298 K} \times \frac{1 J}{1 V C}  

                ln K = -41.28

                    K = e^{-41.28}    

                        = 1 \times 10^{-18}

Thus, we can conclude that the value of the equilibrium constant for the given reaction is 1 \times 10^{-18}.
