Expert Solution

Description

As per the the guidelines, I am answering the first 3 subparts only. To get the rest questions' solutions, please post

them separately on the portal.

a) In order to carry out electrolysis, the reaction set up has to be in a solution not in solid state. So when current is passed through solid lead arsenide, no reaction will occur.
