Homework Help: Chemistry

Posted by Anonymous on Wednesday, December 2, 2009 at 8:27am.

Using the standard reduction potentials, calculate the equilibrium constant for each of the following reactions at 298 K.

10Br- + 2MnO4- + 16H+ -> 2Mn2+ + 8H20 + 5Br2

Work:
2Br- -> Br2 + 2e- (This would be multiplied by 5 to balance out with the upper equation.)

MnO4- + 8H+ + 5e- -> Mn2+ +4H20 (This would be multiplied by 2 to balance out with the upper equation.)

The standard reduction potential for Br- is +1.065.

The standard reduction potential for MnO4- is +1.51.
