6. Given the following galvanic cell: The Mn electrode is immersed in 0.40 M Mn²+. The other electrode (Pt) is immersed in a solution of 0.35 M Cr³+ and 0.25 M Cr²+. A salt bridge connects the two half cells. Pertinent half-reactions and standard potentials: Mn2+ + 2e Mn(s) Eº = -1.180 V Cr³+ + e-Cr²+ Eº = -0.424 V Write the cathodic reaction, anodic reaction and over-all cell reaction. Calculate Eºcell- Calculate Keq- Calculate A,Gº.
