Chemistry-Nernst Equation
NEET Chemistry Nernst Equation MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a schematic diagram of a Daniell cell connected to a voltmeter. If the concentration of Cu²⁺ ions decreases over time, which of the following Nernst equation components directly explains the decrease in the cell voltage?
A
Increase in concentration of Zn²⁺ ions
B
Decrease in temperature
C
Increase in the standard electrode potential
D
Increase in concentration of Cu²⁺ ions
Correct Answer
Option A
Detailed Explanation
According to the Nernst equation, the cell potential depends on the concentrations of the ions involved. As the concentration of Zn²⁺ ions increases and Cu²⁺ ions decrease, the cell potential decreases.
