Variation of current with electrode separation

Answer the following questions:

1. What conclusion was made when the graph was drawn of i (current)  against s (electrode separation in cm)
current is directly proportional to the separation of the electrodes; i µ s
current is inversely proportional to the separation of the electrodes; i µ s-1
current is directly proportional to the square of the separation of the electrodes; i µ s2
current is not directly proportional to the cube of the the separation of the electrodes; i µ s3
2. The current decreases as separation increases because:
ions lose their charge travelling through the solution
the emf is smaller with greater distance
fewer electrons are available on the cathode
the solution now has more resistance.
3.Cations move towards the cathode true false
4.Anions are attracted to the anode true false
5.Cations remove electrons from the cathode and allow more to replace them on the cathode true false
6.Anions deposit electrons on the anode true false
7.emf does not vary with changing separation of the electrodes true false

(attempted)  (maximum 7)

Answer questions on the effect on current of changes in voltage, concentration of solution.
