The equilibrium constant, K_p, equals 3.40 for the isomerization reaction:
cis-2-butene → trans-2-butene.
If a flask initially contains 0.250 atm of cis-2-butene and 0.165 atm of trans-2-butene, what is the equilibrium pressure of each gas?

P(cis-2-butene) = 0.0735 atm and P(trans-2-butene) = 0.250 atm

P(cis-2-butene) = 0.0458 atm and P(trans-2-butene) = 0.156 atm

P(cis-2-butene) = 0.0485 atm and P(trans-2-butene) = 0.165 atm

P(cis-2-butene) = 0.0943 atm and P(trans-2-butene) = 0.321 atm
