Which reaction will occur if each substance is in it's standard state? Assume potentials are given in water at 25 C.
Ni^2+(aq) + 2e- --> Ni(s) -0.28V
Sn^4+(aq) + 2e- --> Sn2+(s) +0.15V
Br2(l) + 2e- --> 2Br^-1(aq) +1.06V
a) Ni2+ will oxidize Sn2+ to give Sn4+
b)Sn4+ will oxidize Br-1 to give Br2
c)Br2 will oxidize Ni(s) to give Ni2+
d)Ni2+ will oxidize Br2 to give Br-1
