5. An electrochemical cell utilizes the following reaction: 2 Fe3+ (aq) + H(g) 2 Fe2+(aq) + 2 H+ (aq) a) Write each 12 reaction and calculate the cell potential under standard conditions? Use the table of Standard Reduction Potentials given on the last page. (3 marks) b) What is the cell potential when [Fe3+] = 3.50 M P H(g) = 0.95 atm [Fe2+] = 0.0010 M and the pH in both half-cells is 4.00
