Question

What is the potential for the electrochemical cell if the activity of H+ in the anodic half-cell is 0.100, the fugacity of H2 in the anodic half-cell is 0.500, and the activity of Cu2+ in the cathodic half-cell is 0.0500? Fugacity is the equivalent term for the activity of a gas.

Answer 1

$E^ocell=E^ocathode-E^oanode$

$E^ocell =34-0$

$E^ocell =34V$
