    Q:

    		 In an electrochemical concentration cell, two identical half reactions are set up with differing concentrations. This is different from galvanic cells which have two different half-cells in the circuit. In a concentration cell, the current is driven by which of the following?
    		 

    A

    		 Electrostatic attraction of electrons to the cell of lower concentration.

    B

    		 Equalization of the cell concentrations due to entropy.

    C

    		 Movement of metal ions from high to low concentration.

    D

    		 Movement of metal ions from low to high concentration.
