# The gas-phase dimerization of butadiene, follows second-order kinetics. At time t 0, pure butadiene.

The gas-phase dimerization of butadiene,

follows second-order kinetics. At time t 0, pure butadiene is introduced into a

vessel at 599 K and 0.832 atm. At time t 60.9 minutes, the total pressure is

0.635 atm. Assume that both gases are ideal and that no back reaction occurs.

a. Find the partial pressure of butadiene at this time.
