Consider the reaction $A(g)+B(I)C(g)$ is carried out only in the gas phase, the reaction takes place

in a reactor with a square cross$-$sectional area. The feed consists of a stream of gaseous A and a

stream of pure liquid B$.$ Liquid B covers the entire bottom of the reactor and evaporates into the

gas stream. The vapor pressure of $B$ remains constant throughout the reactor. The gas flow has

a plug flow behavior. Ignoring the volume of the liquid, determine:

a$)$ The speed law as a function of conversion. I evaluated all possible parameters.

b$)$ What is the value of the reaction rate when the conversion is $50\%.$

DATA: Total pressure $($constant$)=1$ atm. $K=62297\frac{m^3}{k}$mol$*s.T($constant$)=282\mathrm{.}2C.$ Vapor

pressure of $B(P_{vB})=0\mathrm{.}25$atm.$F_{A0}=0\mathrm{.}6818$kmo$\frac{l}{s}.$
