🤓 Based on our data, we think this question is relevant for Professor Petros' class at UNT.
Butane exists as two isomers, n−butane and isobutane.
KP = 2.5 at 25 °C
What is the pressure of isobutane in a container of the two isomers at equilibrium with a total pressure of 1.22 atm?
Recall: The equilibrium constant is the ratio of the pressure or concentration of products and reactants, with each compound being raised to a power equivalent to the stoichiometric coefficient in the chemical equation.
For the reaction aA + bB ⇌ cC + dD, the equilibrium constant is:
where Kp is used for pressures and Kc is used for concentrations.
The Kp expression for the isomerization of n-butane is:
