Answer to relevant QuestionsConsider the galvanic cell based on the following halfreactions: b. Calculate ΔGo and K for the cell reaction at 25oC. c. Calculate cell at 25oC when [Zn2+] = 0.10 M and [Fe2+] = 1.0 × 10–5 M. The Nernst equation can be applied to half reactions. Calculate the reduction potential at 25oC of each of the following half cells. a. Cu/ Cu2+ (0.10 M) (The half reaction is Cu2+ + 2e– n Cu.) b. Cu/ Cu2+ (2.0 M) c. Cu/ ...You have a concentration cell in which the cathode has a silver electrode with 0.10 M Ag+. The anode also has a silver electrode with Ag+(aq), 0.050 M S2O32–, and 1.0 × 1023 M Ag(S2O3)23–. You read the voltage to be ...Electrolysis of an alkaline earth metal chloride using a current of 5.00 A for 748 seconds deposits 0.471 g of metal at the cathode. What is the identity of the alkaline earth metal chloride? A fuel cell designed to react grain alcohol with oxygen has the following net reaction: C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l) The maximum work 1 mole of alcohol can yield by this process is 1320 kJ. What is the ...
