A galvanic cell with a large equilibrium constant has a ___________ cell potential.
A. Positive
B. Variable
C. Negative
D. Zero Voltage
E. Constant
Homework Answers
for a galvanic cell ,standard EMF of the cell is given as
E0(cell) = [RT/nF]ln(K) ;where K is equilibrium constant
so cell potential E0 is directly proportional to natural
logarithm of K.
Hence if equilibrium constant is large in number ,then cell
potential will be
large positive
Answer
option A : Positive
