Consider the galvanic cell based on the following half-reactions: Zn2+ + 2e + Zn e = -0.76 V Cd?+ + 2e → Cd e = -0.40 V %3D a. Determine the overall cell reaction and calculate Ecell (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.) E cell b. Calculate AG' and K for the cell reaction at 25°C. AG kJ K = c. Calculate Ecell at 25°C when Zn2+] Ca2+ = 0.10 M and = 7.2 x 10-5 M. Ecell
