The standard reduction potential for the half cell:
NO⊖3(aq)+2H⊕+→NO2(g)H2O is 0.78 V
The reduction potential in 8 M H⊕ is: (in V)
Assume all the other species to be at unit concentration. ( write your answer to nearest integer)
The standard reduction potentail for the half cell
NO⊖3(aq)+2H⊕(aq)+e−→NO2(g)+H2O(g) is 0.78 V.
By Nernst equation for the above half cell reaction.
(a) Ecell=E⊖cell−0.0591nlog[NO2][H2][NO⊖3][H⊕]2
= 0.78−0.5911log1×11×(8)2
= 0.78 + 0.059 log 64
=0.887V.
