NEET Chemistry Nernst Equation MCQ Question

Type: MCQ-diagram based-Medium-Class 12

Consider a diagram depicting an electrochemical cell where the Nernst equation is used to determine the cell potential. If the concentration of Zn2+ ions increases while the concentration of Cu2+ ions decreases, which of the following statements about the cell potential is correct?

Question diagram
A

The cell potential decreases over time.

B

The cell potential remains constant.

C

The cell potential increases over time.

D

The cell potential fluctuates randomly.

Correct Answer

Option A

Detailed Explanation

According to the Nernst equation, as the concentration of Zn2+ increases and Cu2+ decreases, the reaction quotient Q increases, leading to a decrease in the cell potential.
