Express the rate of reaction (-rA) solely as a function of conversion for a gas-phase reaction, A → B + 2C, in a plug flow reactor. The feed contains 50% of inert gas. What is the total species concentration in the effluent at 80% conversion relative to the initial concentration of all species (i.e., what is CT/CTo)?
