Question
Which of the following redox reactions are spontaneous --
SN2+(aq)+BA(s)->Sn(s)+Ba2+(aq)
2AG+(ag)+2Cl-(aq)->2Ag(s)+C12(g)
ZN(s)+F2(g)->2F-(aq)+Zn2+(aq)
2LI(s)+Co2+->(aq)->2Li+(aq)+Co(s)
2I-(aq)+K+(aq)->I2(s)+K(s)
I believe it is A, C & E
SN2+(aq)+BA(s)->Sn(s)+Ba2+(aq)

I don't know and you can look up (and probably have) the E values. If Ecell is +, the cell is spontaneous. Note that AG, ZN and SN don't mean anything.
