Answer:
The electrical current in electrolysis act as a catalyst driving a reaction in forward direction because when the electric current is allowed to the electrodes, the particles in the solution starts movement towards electrodes. Before this current, the particles inside the solution are static. If a solution contain sodium chloride so when the electrical current is passed. Sodium moves to the negative electrode while chlorine moves towards positive electrode and both the atoms are separated from each other and the reaction is completed.
