Chemistry-Nernst Equation
NEET Chemistry Nernst Equation MCQ Question
Type: MCQ-fact-Hard-Class 12
What is the correct form of the Nernst equation for a general electrochemical reaction?
A
E(cell) = E°(cell) - (RT/nF) ln(Q)
B
E(cell) = E°(cell) + (RT/nF) ln(Q)
C
E(cell) = E°(cell) + (nF/RT) ln(Q)
D
E(cell) = E°(cell) - (nF/RT) ln(Q)
Correct Answer
Option A
Detailed Explanation
The Nernst equation for a general electrochemical reaction is given as E(cell) = E°(cell) - (RT/nF) ln(Q), which relates the cell potential to the reaction quotient Q and standard cell potential.
