Question

For the reaction, CO(g) + Cl2(g) ⇌ COCl2(g) the Kp/Kc is equal to

  • 1/RT

  • 1.0

  • √RT

  • RT

Answer

A.

1/RT

Kp =Kc (RT)Δn
Δn = sum of coefficients of gaseous products
Sum of coefficients of gaseous reactants.
CO (g) + Cl2 (g) → COCl2 (g)
Δn = 1-2 = -1
Kp = Kc (RT)-1
Kp/Kc = (RT)-1 
1/RT
