Question: When given the following information: Cr2O72- + 14H+(aq) + 6 2 Cr3+ + 7H2O(l) E0r = 1.23V Al3+(aq) + 3 Al(s) E0r = -1.66V Determine

When given the following information:

Cr2O72- + 14H+(aq) + 6 2 Cr3+ + 7H2O(l) E0r = 1.23V

Al3+(aq) + 3 Al(s) E0r = -1.66V

Determine if the following redox reaction will occur spontaneously as it is written:

2Cr 3++ 7H2O(l) + 2Al3+(aq) Cr2O72- + 14H+(aq) + 2Al(s)

You will need to support your answer with calculations.
