The following thermodynamically favored reaction takes place in an acidified galvanic cell.

O2(g) + 2 H2S(g)  2 S(s) + 2 H2O(l)

a. What is the half reaction that takes place at the anode?

b. What is the half reaction the takes place at the cathode?

c. Calculate the standard cell potential, Eo

cell.

d. What must the partial pressures of the reactants be in order to produce the

voltage in part c?

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
