The emf of cell  is 0.83 V at 298 K. It could be increased by:

Canvas Classes · Accepted Answer

Strategy:
 Apply Le Chatelier's principle to the Nernst Equation. The cell EMF depends on the ratio of species in the reaction quotient (). Increasing reactants or decreasing products shifts the equilibrium to favor the forward reaction (increasing EMF).

Step 1: Write the cell reaction
From the notation :
- Anode: 
- Cathode: 
- Net Reaction:

Step 2: Apply the Nernst Equation

Step 3: Analyze concentration effects
To increase , we must decrease the value of the  term:
- Increase  (reactant c
