Question

A(g) + 2B(g) 2C(g)

If Kp for the above reaction is 4.55 x 10-2, in what direction will the reaction proceed to establish equilibrium if the pressures of A, B, and C are 0.250 atm, 0.750 atm, and 0.080 atm respectively?

proceeds in the forward direction to establish equilibrium

it is at equilibrium already

proceeds in the reverse direction to establish equilibrium

option 1:

proceeds in the forward direction to establish equilibrium

option 2:

it is at equilibrium already

option 3:

proceeds in the reverse direction to establish equilibrium

Explanation / Answer

= [C]2 / [A] [B]2

= [0.08]2 / [0.25] [0.75]2

= 4.55 x 10-2

Hence Option 2 it is at equilibrium already
