The elementary gas phase reaction $A+B2C$ is to be carried out in a packed bed reactor with $100$ kg catalyst under isothermal conditions with pressure drop.

a$)$ Calculate the conversion exiting the reactor.

$y=\frac{P}{P0},Gas$ phose $T=T_0$

$C_j=C_{T_0}\frac{F}{F_j}\frac{P}{n_0}\frac{T_0}{T_0}$

b$)$ Calculate the pressure exiting the reactor.
