对于电池Pt│H2(p?)│NaOH(0.01mol·kg-1)│O2(p?)│Pt其电极电位和电池电动势的表示正确的是（）

A.E右=E?(O2/OH-)-(RT/F)ln[a(OH-)/a1/4(O2)]

B.E左=E?(H2O/H2,OH-)-(RT/F)ln[a1/2(H2)·a(OH-)]

C.E左=E?(H+/H2)-(RT/F)ln[a1/2(H2)/a(H+)]

D.E=E右-E左

正确答案：E右=E?(O2/OH-)-(RT/F)ln[a(OH-)/a1/4(O2)]；E左=E?(H2O/H2,OH-)-(RT/F)ln[a1/2(H2)·a(OH-)]；E左=E?(H+/H2)-(RT/F)ln[a1/2(H2)/a(H+)]；E=E右-E左
