Non-stoichiometric cuprous oxide, 'Cu2 ...

Non-stoichiometric cuprous oxide, 'Cu_2 O' can be prepared in laboratory. In this oxide, Copper to oxygen ratio is slightly less than '2: 1 .' Can you account for the fact-that this substance is a p-type semiconductor?

Since. the C0pper to oxygèn ratio is slightly less than 2: 1 , it means that .Cu_2 O. has metal deficiency defect. In such a crystal. when an electron moyes frow .Cu^+. to. .Cu^24. ión. a positive, hole is created, which can move from one position to another. Thus current flow is due to the movement of positive holes and it is a p-type semiC0nductor.

F centre is an example of metal excess defect due to the presence of extra cations at interstitial sites. Zinc oxide is white in colour at room temperature, on heating it loses oxygen and turns yellow. ZnO overset("Heat")toZn^(2+)+(1)/(2)O_(2)+2e^(-) Now there is excess of zinc in the crystal and its formula becomes Zn_(1+x) O. the excess of Zn^(2+) ions move to interstitial sites and the electrons to neighbouring interstitial sites. There are many solids which are difficult to prepare in the stiochiometric composition and contain less amount of the metal as compared to stiochiometric proportion. a typical example of this type is FeO which is mostly found with a composition of Fe_(0.95) . it may actually range from Fe_(0.96) O. Q. In Fe_(0.95) O:

Which of the following statements are correct? Fuel cells are galvanic cells in which the chemical energy of fuel is directly converted into electrical energy. Type of fuel cell is a hydrogen - oxygen fuel cell. It consists of two electrodes made up of two porous graphite impregnated with a catalyst (platinum, silver, or metal oxide). The electrodes are placed in aqueous solution of NaOH. Oxygen nad hydrogen are continuously fed into the cell. Hydrogen gets oxidized to H^(oplus) which is neutralized by overset(Θ)(OH) , ie., anodic reaction. H_(2) hArr 2H^(oplus) + 2e^(-) 2H^(oplus) + 2 overset(Θ)(OH) hArr 2H_(2)O H_(2) + 2 overset(Θ)(OH) hArr 2H_(2)O + 2e^(-) At cathode, O_(2) gets reduced to overset(Θ)(OH) i.e., O_(2) + 2H_(2)O + 4e^(-) hArr overset(Θ)(4)OH Hence, the net reaction is 2H_(2) + O_(2) hArr 2H_(2)O The overall reaction has Delta H= -285.6kJ mol^(-1) and Delta G= -237.4kJ mol^(-1) " at " 25^(@)C A fuel cell is I.

The efficiency of H_(2)-O_(2) fuel cell is 70 to 75%
