The equilibrium constant, Kp, 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 0.145 atm of trans-2-butene, what is the equilibrium pressure of each gas?
A. 0.037 and 0.125 atm, respectively.
B. 0.48 and 0.165 atm, respectively.
C. 0.074 and 0.250 atm, respectively.
D. 0.085 and 0.290 atm, respectively.
E. None of these.
