Correct Answer - b
`Ti^(3+)+2e^(-)rarrTi^(+):E_(1)^(@)=1.26V`
`Ti^(+)+e^(-)rarrTi:E_(2)^(@)=-0.336V`
`Ti^(3+)+3e^(-)rarrTi:E_(3)^(@)=?`
`DeltaG_(3)=DeltaG_(1)+DeltaG_(2)`
`n_(3)E_(3)^(@)F=n_(1)E_(1)^(@)F+n_(2)E_(2)^(@)F`
`3E_(2)^(@)=2xx1.26+1xx(-0.336)`
`E_(3)=(2.52-0.336)/(3)`
`=(2.184)/(3)=0.728V`
