Answer to Question #350120 in Physical Chemistry for Amani

Question

Given that Zn/Zn2+(1M)//Cu2+(1M)/Cu

(a) calculate the emf of the cell

(b) predict if the reaction is spontaneous or non spontaneous

Given that Zn/Zn2+ E=0.34V, Cu2+/Cu E=1.10V

Answer 1

E=0.33+0.76=1.09 , it will be spontaneous since G=-nFE, and our case is positive E, G - is negative
