Complete Question
A voltaic cell utilizes the following reaction and operates at 298 K:
3Ce4+(aq)+Cr(s)→3Ce3+(aq)+Cr3+(aq).
What is the emf of this cell under standard conditions? Express your answer using three significant figures.
Answer:
The value is
Explanation:
From the question we are told that
The ionic equation is
Now under standard conditions the reduction half reaction is
And the oxidation half reaction is
The emf of this cell under standard conditions is mathematically represented as
substituting values
