Question- The galvanic cell described by the balanced chemical equation has a standard emf (electromotive force) of 4.05 V. Calculate the value (J) for the maximum electrical work that the cell can do under standard conditions.
Round your answer to three significant figures.
F2(g) + Mn(s) ? 2F-(aq) + Mn2+(aq)
St. Red. Pot. (V)
Mn2+/Mn -1.18
F2/F- +2.87
Faraday's Constant
F = 96485 C
Express your answer using two significant figures.
The unit of S was the J/(mol*K) the book said. But, in delta S, why the unit is J/K? I just think when I want to calculate delta S, sum of products's S - sum of reactants's S, so the unit of delta S is same as S I thought. What is it
