MCAT Question of the Day


  • Q:

    Given the following information:
    Au3+ + 3e- → Au E° = 1.50 V
    Cu 2+ + 2e- → Cu E° = 0.34 V

    What is the standard potential of the following reaction? Is it spontaneous?

    2Au + 3Cu2+ → 2Au3+ + 3Cu


     

    A

    1.16 V, spontaneous

    B

    -1.16 V, non-spontaneous

    C

    1.98 V, spontaneous

    D

    -1.98 V, non-spontaneous
