We don't do homework but we can help you understand. What about the problem do you not understand? Do you know to look up the cell potential for the Mn to Mn^+2 and add it to the cell potential for the Ce^+4 ==>Ce^+3? That should give you the cell potential for the reaction...

During a particular thunderstorm, the electric potential difference between a cloud and the ground is Vcloud - Vground = 4.3 108 V, with the cloud being at the higher potential. What is the change in an electron's electric potential energy when the electron moves from the ...
