Question

What is the calculated value of the cell potential at 298K for an electrochemical cell with the following reaction, when the F2 pressure is 3.62x10* atm, the F concentration is 1.18M, and the Cr3+concentration is 1.29M? 3F2(g) +2Cr(sF(aq) + 2Cr (aq) Answer:V The cell reaction as written above is spontaneous for the concentrations given: atm, What is the calculated value of the cell potential at 298K for an electrochemical cell with the following reaction, when the H2 pressure is 6.80x10 the H concentration is 1.47M, and the Mg2+ concentration is 1.55x101M? 2H (ag) Mg(Mg(aq) Answer: The cell reaction as written above is spontaneous for the concentrations giver true false
