Answer to Question #152120 in Chemistry for Alexis

Question

For the formation of NH3 from N2 and H2, N2(g) + 3H2(g) ↔ 2NH3(g) Kp = 4.34 x10-3 at 300ºC.

What is the value of Kp for the reverse reaction?

Answer 1

Solution:

The balanced chemical equation for the reverse reaction:

2NH₃(g) ↔ N₂(g) + 3H₂(g)

The equilibrium expression for the reaction system:

K_p^r - K_p for the reverse reaction.

K_p = 4.34×10^-3

Hence,

Answer: Tthe value of K_p for the reverse reaction is 2.30×10².
