A) Positive
B) Negative
C) Zero
D) Infinite
Correct Answer: A
Solution :
EMF = [s.r.p. of cathode?s.r.p of anode] Where s.r.p. = Standard reduction potential\[\] If EMF is positive then the reaction is spontaneous For e.g. in Galvanic cell EMF = 1.1 volt Cathode is made of copper Anode is made of Zinc EMF = 0.34 ?(? 0.76) = 1.1 volt.You need to login to perform this action.
