Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
In electrochemistry:
\[
\Delta G = -nFE
\]
Chemical driving force is Gibbs free energy, balanced by EMF.
Step 1: Identify chemical driving force.
\[ \text{Driving force} = \Delta G \]
Step 2: Relate to electrical work.
\[ \Delta G = -nFE \] So EMF opposes/balances chemical force. Final Answer: \[ \boxed{\text{Electromotive force}} \]
