Homework Help: Chem 12

Posted by Sam on Thursday, February 12, 2009 at 2:25am.

Given the two reactions:
5Fe2+(aq) + MnO4-(aq) + 8H+(aq) --> 5Fe3+ (aq) + Mn2+(aq) + 4H2O(l)

2MnO4-(aq) + 5C2O42-(aq) +16H+ --> 2Mn2+(aq) + 10CO2(g) + 8H2O(l)

A.) Which reaction will occur at a faster rate?
B.) Explain the reason for this result by comparing what is involved in changing Fe2+ to Fe3+ to what is involved in changing C2O42- to 2CO2
