The standard reduction-potential for the half-cell : `No_(3)^(-) (aq) + 2H^(+) + e^(-)rightarrow No_(2) ((g))+H_(2)O` is 0.78V
(i) Calculate the reduction – potential in 8M H+. (ii) What will be the reduction-potential of the half –cell in a neutral solution? Assume all the other species to be at unit concentration.

Answer

`0.046 V`
