Question
Define the following terms:
- Limiting molar conductivity.
- Fuel cell.
✓
Answer
- The molar conductivity when concentration approaches to zero is called limiting molar conductivity.
- A fuel cell is a device which converts energy produced during the combustion of fuels like hydrogen, methane, methyl alcohol etc. directly into electrical energy. One such successful fuel cell is hydrogen-oxygen fuel cell.
