Consider the following half-cell reaction and associated standerd half-cell potentials and determine the maximum  voltage thatr can be obtained by combination resulting in spontenous process :   `AuBr_(4)^(-)(aq)+3e^(-)toAu(s)+4BR^(-)(aq), E^(@)=-086V`   `Eu^(3+)(aq)+e^(-)toEu^(2+)(aq), E^(@)=-043V`   `Sn^(2+)(aq)+2e^(-)toSn(s), E^(@)=-0.14V`   `IO^(-)(aq)+H_(2)O(l)+2e^(-)toI^(-)(aq)+2OH^(-), E^(@)=+0.49V`
