Stoichiometry- Gas Phase

[@alqahtanifaisal8820]

Thanks,I would appreciate your help

[@stellabeauty01]

How would I do this with a system of complex reactions

[@alqahtanifaisal8820]

Hi, I did not get Fj , you first said Ft and then changed to Fj but you did not change it when doing the ratio . Can you please explain what is it ?

[@alqahtanifaisal8820]

And also why having Vj when expressing in terms of conversion ,isn't it suppose to be the stoichiometric ratio?
