The elementary gas reaction

$2A+B+C$

is carried out isothermally in a PFR with no pressure drop. The feed is equal molar in A and B and the entering concentration of $A$ is $0\mathrm{.}1mo\frac{l}{d}{m}^2.$

a$)$ Determine the entering concentration $(mo\frac{l}{d}{m}^3)$ of B$?$

$(1$Marks$)$

b$)$ Establish the concentrations of A and $C(mo\frac{l}{d}{m}^3)$ at $25\%$ conversion ofA? $(2$ Marks$)$c$)$ Calculate is the concentration of B $(mo\frac{l}{d}{m}^3)$ at $25\%$ conversion of A$?(2$ marks$)$
