Question
We know that the relationship between Kc and Kp is Kp = Kc (RT)∆n What would be the value of ∆n for the reaction \[\ce{NH4Cl (s) ⇌ NH3 (g) + HCl (g)}\]
Options
1
0.5
1.5
2
Solution
2
Explanation:
The relationship between Kp and Kc is Kp = Kc (RT)∆n
Where ∆n = (Number of moles of gaseous products) – (Number of moles of gaseous reactants)
For the reaction,
\[\ce{NH4Cl (s) ⇌ NH3 (g) + HCl (g)}\]
∆n = 2 – 0 = 2
