Answer : Option A) 45.5%
Explanation : We use the formula of calculating energy efficiency which is as,
η (in %)= [
] X 100
where η is energy efficiency,
and P values are for energy out and in.
So plugging the given values, we get,
η (in %) = (11825.5 / 25978.8) X 100 = 45.5 %

Nitric acid(HNO3) is a strong acid so most of its component will dissociate into an ion form. When dissolved into water, nitric acid will have this reaction
HNO3= 1 H
+ NO3
For every 1 mol of HNO3, there will be 1 mol of H+ ion and NO3- ion formed, which makes a total of 2 ions(degree of dissociation = 2).
Then for 2 moles of HNO3 it would be: 2 moles * 2= 4 moles of ion
