Cell Potential Under Nonstandard Conditions

AP Chemistry· difficulty 3/5

T (K) E Q > 1, n=2

For Q > 1, why does the Nernst plot show E decreasing as T increases?

  • A

    Because Faraday's constant decreases

  • B

    Because (RT/nF) ln Q grows with T when Q > 1

  • C

    Because E° decreases with T

  • D

    Because n increases with T

Explanation

With Q>1, ln Q>0 and (RT/nF)·ln Q rises with T, so E = E° − (RT/nF)ln Q falls.
