The equilibrium constant (K) for the isomerization reaction of cis-2-butene to trans-2-butene is 3.4 at 25 °C. This means that the forward reaction (cis-2-butene to trans-2-butene) is favored at equilibrium. Therefore, the system will shift to the right to reach equilibrium and produce more trans-2-butene. This will reduce the concentration of cis-2-butene and increase the concentration of trans-2-butene until the equilibrium constant is reached. Therefore, the correct answer is B, it will shift right.

The Equilibrium Constant,Kp,equals 3

The Equilibrium Constant,K_p,equals 3
