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`
A. `+0.72`
B. `+1.54`
C. `+1.00`
D. `+1.35`
