question 144

Multiple Choice

For the isomerization reaction:
Butane ⇌ isobutane
K_p equals 25 at 500°C.If the initial pressures of butane and isobutane are 20.atm and 0.0 atm,respectively,what are the pressures of the two gases at equilibrium?

• A)P(butane)= 0.77 atm and P(isobutane)= 19.2 atm
• B)P(butane)= 0.80 atm and P(isobutane)= 20.atm
• C)P(butane)= 19.2 atm and P(isobutane)= 0.77 atm
• D)P(butane)= 20 atm and P(isobutane)= 0.80 atm
