Answer: Δn for the following equation in relating Kc to Kp is 2.
Explanation:
The balanced chemical equation is:

Relation of
with
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles =
Putting values in above equation, we get:
Thus the value of Δn for the following equation in relating Kc to Kp is 2.
An acid, acids have a pH less than 7
