Consider the cell below. Please note that this cell may or may not obey the conventions of a standard cell diagram. Assume the cell is working spontancously under standard conditions. A B Salt bridge H. K. Image: Rectangle I in a beaker in a solution of J. An arrow F points away from rectangle I and an arrow E points toward rectangle I. The rectangle I is joined by a line another rectangle L in a separate beaker. On this line, an arrow labelled A points toward I and an arrow labelled B points to L. Rectangle L in a beaker in a solution of K. An arrow H points away from rectangle Land an arrow G points toward rectangle L.A salt bridge joins the beakers. On this salt bridge, an arrow labelled C points toward I and an arrow labelled D points to L. End of image. | = Q J = QNO3 Reduction Potential Q = minus 0.400 V K = RNO3 Reduction Potential R = minus 0.200 V L = R Match the each statement to the letter that best describes it. Some answers may be used more than once. of: C. E.
