Homework Help: Chem

Posted by Anonymous on Wednesday, April 10, 2013 at 8:10pm.

Calculate ΔGo (in J) for 1 moles of electron(s) in each half-reaction and a standard potential of 0.34 V.

I got .86


Calculate Keq for 2 moles of electron(s) in each half-reaction and a standard potential of (-0.44) V.

I got -.36


Calculate the potential for: Br2(l) + 2Cl-(aq) → Cl2(g) + 2Br-(aq) Use E = -.300 V

when the concentrations of the soluble species are as follows:

[Cl-] = 0.46 M, [Br-] = 2.0x10-3 M, PCl2 = 3.9x10-2 atm

I got -.32

All of these are wrong :( can someone please help?
