The equilibrium constant, Kp, equals 3.40 at 25 ∘C for the isomerization reaction: cis-2-butene ⇋ trans-2-butene. If a flask initially contains 41.00 atm of trans-2-butene and 10.00 atm of cis-2-butene, in what direction will the system shift to reach equilibrium?

Respuesta :

Answer:

Equilibrium will go to backward direction

Explanation:

The equilibrium reaction is :-

cis-2-butene ⇋ trans-2-butene

The equilibrium constant, Kp for the reaction = 3.40

The reaction quotient is:-

[tex]Q_p=\frac{P_{trans-2-butene}}{P_{cis-2-butene}}[/tex]

Given that :- Pressure of cis-2-butene = 10.00 atm

Pressure of trans-2-butene = 41.00 atm

Thus,

[tex]Q_p=\frac{41.00}{10.00}=4.1[/tex]

Qp > Kp, equilibrium will go to backward direction
