i need this asap. For the following Gas phase decomposition reaction $aA+bBdD$ is carried out in a flow

reactor at $10$atm and $400K.$ The feed consists of $x,y$ and $Z$ mole fractions of $A,B$ and Inert

respectively. Part of the stoichiometric table is as follows:

a$)$ What is the rate of reaction when $x$ reaches $60\%?$

b$)$ If the total molar feed rate is $50mo\frac{l}{m}in$ and the feed exhibits a conversion of $20\%,$ what

will be the volume of a Continuous Stirred Tank Reactor $($CSTR$)$ given that the exit conversion

of the reactor is $80\%?$ Ignore pressure drops.
