Lipids functions by storing energy for organisms, as chemical messengers between cells, tissues, and organs, and they also function as structural parts of cell membranes.
Always report to a teacher or supervisor if anything goes wrong in the lab.
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
