Correct answer: .. Cell reaction Cu2+(aq) +Zn Cu (s) + Zn2+ (aq) 0.02M 0.04M E0cell = o Cu | Cu2 E  –  o Zn | Zn2 E  = 0.34 – (–0.75) = 1.1V Ecell = E0cell – 0.059 log ] [Cu ] [Zn 2   = 1.1 – 0.059 log       . 04 . = 1.1 – 0.03 log 2 = 1.1 – 0.03 × 0.30 = 1. 0915 = 1.09V = 109×10-2V Ans = 109
