I already understand parts a & b, but can someone explain part c) to me?
Consider the following overall cell reaction: (3 points) Cr_2O_7^2- + 14H^+ + 6I^-1 rightarrow 2Cr^3+ + 3I_2 + 7H_2O write the cell reactions at the cathode and anode. What is the E^0 for the cell? What is the emf of the cell (Ecell) when [CrÂ_2O_7]^2- = 1.5 M, [H^+] = 1.0 M, [I^-] = 1.0M, and [Cr^3+] = 1.7 times 10^-5M ? Cr_2O_7^2- + 14H^+ + 6e^-1 rightarrow 2Cr^3+ +7HzO E degree = + 1.33V 2I^-1 rightarrow I_2 + 2e^-1 E degree = +0.54 V
