You have created a galvanic cell in order to perform thefollowing UNBALANCED reaction. First, balance the reaction. Br- +Ag+ → Br2 + Ag
Part 1: You look up the appropriate reduction potentials forthis reaction, and you find the following: Half Reaction Eo (V) Br2+ 2e- → 2Br- 1.11 Ag+ + e- → Ag 0.77 What is the voltage of thereaction given in the introduction? Br- + Ag+ → Br2 + Ag
Part 2: We will use this voltage to calculate K and ΔGo. Fromyour balanced reaction, what number will you use for n?
Part 3: In order to calculate K from ΔG, we must select theappropriate value of R. The question, then, is what units will ΔGohave after the calculation. Note that Faraday's constant (F) has avalue of 96500 C/mol, E has units of V, n has units of moles, and 1V = 1 J/C. Which of the following is the correct value for R? A0.00831 kJ/(mol*K) B 0.0821 L*atm/(mol*K) C 8.31 J/(mol*K)
Part 4: What is the value of ΔGo for the reaction determined inpart 1 (in J/mol)?
Part 5: If the above reaction is carried out at 298 K, what isthe value of K?
