Match the Following
| List-I (Use) | Item | Matches with | List-II (Substance) |
|---|---|---|---|
| A | Electrodes in batteries | II | Polyacetylene |
| B | Welding of metals | III | Oxyacetylene |
| C | Toys | I | Polypropylene |
Show Hint
- A–III, B–II, C–I
- A–II, B–III, C–I
- A–II, B–I, C–III
- A–I, B–II, C–III
The Correct Option is B
Solution and Explanation
- A) Electrodes in batteries → Polyacetylene (II): Polyacetylene is a conducting polymer used in electronic devices including battery electrodes.
- B) Welding of metals → Oxyacetylene (III): Oxyacetylene flame (from reaction of oxygen and acetylene) is used for metal welding due to its high temperature.
- C) Toys → Polypropylene (I): Polypropylene is a lightweight, durable plastic used in making toys.
Top Questions on Electrochemical Cells
An electrochemical cell is fueled by the combustion of butane at 1 bar and 298 K. Its cell potential is $ \frac{X}{F} \times 10^3 $ volts, where $ F $ is the Faraday constant. The value of $ X $ is ____.
Use: Standard Gibbs energies of formation at 298 K are:
$ \Delta_f G^\circ_{CO_2} = -394 \, \text{kJ mol}^{-1}; \quad \Delta_f G^\circ_{water} = -237 \, \text{kJ mol}^{-1}; \quad \Delta_f G^\circ_{butane} = -18 \, \text{kJ mol}^{-1} $
