How do nonmetals conduct electricity? well . by giving up electrons . poorly . better than metals.

Usually poorly, especially at room temperature for most of them. The gases do not conduct. Some that are marginally non metals (silicon germanium and graphite) conduct passably well but do not conduct as well as copper or silver.

Non metals do not have easily freed electrons and that is why they do not conduct electricity.

answer; /// i do believe that the correct answer is (a) boiling

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
