Refer to galvanic cell. 0.010 M Zn2+ in left cell and 1.5 M Ag+ in right cell. Standard reduction potentials are as follows: Zn2+ + 2e- --> Zn E= -0.76 V Ag+ + e- --> Ag E= 0.80 V A. Based on the standard reduction potential, which species is oxidized when current is allowed to flow? B. Calculate the value of Q, the reaction quotient, for this cell reaction. C. Calculate the actual cell potential at 25 degrees C.
