If electrolysis of water is carried out for a time duration of 2 hours, how much electric current in amperes would be required to liberate $$100 \mathrm{~ml}$$ of $$\mathrm{O}_2$$ gas measured under standard conditions of temperature and pressure?
Match the items in Column I with their description in Column II
| S.No. | Column I | S.No. | Column II |
|---|---|---|---|
| A | Kappa K | P | Intensive property. |
| B | $$\mathrm{E_{cell}^0}$$ | Q | Extensive property. |
| C | Molar conductivity | R | Decreases with decrease in concentration of both strong and weak electrolytes. |
| D | $$\mathrm{\Delta G_{cell}}$$ | S | Increases with dilution. |
When Lead Storage battery is in the process of getting charged which one of the following reactions takes place?
The reaction taking place in a galvanic cell is as given
$$\mathrm{A}(\mathrm{s})+\mathrm{B}^{2+}\left(\mathbf{1} \mathbf{1} \mathbf{1 0} \mathbf{0}^{-\mathrm{M}} \mathbf{M}\right) \rightarrow \mathrm{B}_{(\mathrm{s})}+\mathrm{A}^{2+}(0.1 \mathrm{M}).$$
The emf of the cell is $$+2.651 \mathrm{~V}$$. If the standard emf of the cell is $$+2.71 \mathrm{~V}$$, what is the value of $$\mathrm{X}$$ ?
