What is the change in potential of following cell Zn ( s ) | array c Zn n ²⁺ 1 M array | gathered Pb ²⁺ 1 M gathered Pb ( s ) if concentration of ions at anode is increased 10 times?

Options

  1. ADecreases by 0.0296 volt
  2. BIncreases by 10 volt
  3. CDecreases by 10 volt
  4. DIncrease by 0.0296 volt

Correct answer

A. Decreases by 0.0296 volt

Step-by-step solution

E _ cell = E _ cell ^0- 0.0591 2 [ Zn ⁺² ] [ Pb ⁺² ] As conc. of Zn ⁺² increases 10 times, E _ cell decreases by 0.0296 volts.
