Equilibrium Question 598

Question: For the reaction $ {N_{2(g)}}+{O_{2(g)}} $ ⇌ $ 2N{O_{(g)}} $ , the value of $ K_{c} $ at $ 800^{o}C $ is 0.1. When the equilibrium concentrations of both the reactants is 0.5 mol, what is the value of $ K_{p} $ at the same temperature [KCET 2005]

Options:

A) 0.5

B) 0.1

C) 0.01

D) 0.025

Show Answer

Answer:

Correct Answer: B

Solution:

$ {N_{2(g)}}+{O_{2(g)}} $ ⇌ $ 2N{O_{(g)}} $

$ K_{c}=0.1,,K_{p}=K_{c}{{(RT)}^{\Delta n}} $

$ \Delta n=0,,K_{p}=K_{c}=0.1 $
