In an electrochemical cell, q = 0.0010 and k = 0.10. what can you conclude about ecell and e∘cell? in an electrochemical cell, = 0.0010 and = 0.10. what can you conclude about and ? both ecell and e∘cell are negative. ecell is negative and e∘cell is positive both ecell and e∘cell are positive. ecell is positive and e∘cell is negative.

If there is electrochemical cell where Q = 0.0010 and K = 0.10 then the truth about Ecell and E°cell is,
Ecell is positive and E°cell is negative.
E° = (RT/nF) InQ = (RT/nF) × In(K/Q) = Positive.
Since ( K/Q) = 100 then In(K/Q) = positive

In an electrochemical cell, where q = 0.0010 and k = 0.10 then the ecell is positive and e∘cell is negative.

Option (D) is correct.

What is an electrochemical cell ?An electrochemical cell is a device that may produce electrical energy from chemical reactions or use electrical energy to initiate chemical reactions. The galvanic, or voltaic, cell, named after Luigi Galvani and Alessandro Volta, is an example of this type of cell. The electrochemical cell consist of four parts:Anode: where oxidation occurs.Cathode: where reduction occurs.External pathways to allow the flow of electrode.Salt bridge or porous bridge.Electrolysis is a way of using a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction in chemistry and manufacturing.

Thus, the correct option is (D),  e cell will be positive and e∘cell will be negative.
