Question

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.

Answer 1

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
