Answer to Question #323906 in Organic Chemistry for Lipika

Question

Define equilibrium constant and for the following reaction

2NH3(g) ⇌ 2N2(g) +3H2 (g)

i. Write the expression for Kc.

ii. Relate Kc to Kp, and

iii. Relate Kc

to Kx

Answer 1

Kc​=[N2​][H2​]3
[NH3​]2​,Kp​=pN2​×pH2​3​
pNH3​2​​Δn=2−(1+3)=−2∴Kp​=Kc​(RT)Δn=Kc​(RT)−2=Kc​/(RT)2
