Question

Define the following terms:
(i) Fuel cell
(ii) Limiting molar conductivity $\left({\bigwedge }^{o}m\right)$

Answer 1

Fuel cell:-

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction.

Limiting Molar Conductivity:-

Molar conductivityis defined as the conductivityof an electrolyte solution divided by the molar concentrationof the electrolyte, and so measures the efficiency with which a given electrolyte conducts electricity in solution. It is the conducting power of all the ions produced by dissolving one mole of an electrolyte in solution.
