The free energy change for a reaction ΔG is an extensive property. What is an extensive property? Surprisingly, one can calculate ΔG from the cell potential for the reaction. This is surprising because is an intensive property. How can the extensive property ΔG be calculated from the intensive property %?
Answer to relevant QuestionsWhen magnesium metal is added to a beaker of HCl(aq), a gas is produced. Knowing that magnesium is oxidized and that hydrogen is reduced, write the balanced equation for the reaction. How many electrons are transferred in ...Calculate ΔGo and K at 25oC for the galvanic cell reactions in Exercise 21. Reactions in exercise 21. AlF63– + 3e- → Al + 6F2 Using data from Table 11.1, calculate the equilibrium constant at 25oC for the reaction Al3+(aq) 1 6F2(aq) ⇌ AlF63–(aq) Table 11.1 Consider the cell described below: Al | Al3+(1.00 M) | | Pb2+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.60 mol/ L. (Assume T = 25oC.) Consider a galvanic cell at standard conditions based on the following half reactions: Au3+ + 3e- → Au ϐo = 1.50 V Fe3+ + e- → Fe2+ ϐo = 0.77 V When enough NaCl(s) is added to the compartment containing gold to make ...
