B.
As you can see both NO and NH3 have 4 moles therefore it is 4:4 between the molecules or in other words a 1:1 ratio in simplest forms
Answer:
The answer to your question is pH = 2.2
Explanation:
Data
pH = ?
moles of HCl = 0.927
volume = 150 l
Process
1.- Calculate the Molar concentration of HCl
Molarity = moles / volume (L)
Molarity = 0.927 / 150
= 0.00618
2.- Calculate the pH
pH = -log [HCl]
Substitution
pH = -log [0.00618]
Result
pH = 2.2
Explanation:
Formula to calculate standard electrode potential is as follows.

= 0.535 - 1.065
= - 0.53 V
Also, it is known that relation between
and K is as follows.

ln K =
Substituting the given values into the above formula as follows.
ln K =
=
ln K = -41.28
K =
= 
Thus, we can conclude that the value of the equilibrium constant for the given reaction is
.
