Nernst equationMediumQuestion 710006
Question
The Nernst equation for a cell reaction at 298 K is E = E° − (0.0592/n) log Q. For n = 2 and Q = 100, E − E° is:
- A−0.0592 VCorrect
- B+0.0592 V
- C−0.1184 V
- D+0.1184 V
Correct answer
−0.0592 V
Explanation
E − E° = −(0.0592/2) log 100 = −(0.0296)(2) = −0.0592 V.
