Hi everyone,


How the Volume of CB0=200 at XA=1 becomes -100B and volume of Ci0 still remains 100i (please read the document in attachment)


Is there any formula to apply for other cases for example A+2B -> 4R



thank you so much

Attached the supportive document from O.Levenspiel .

Same you may find pointers in the link attached.



Considering the reaction and 100% conversion of reactant A, you will find a deficit 0f 100 of reactant B and the Inert remains constant thus V@ xA=1 0 A+(200-300) B+100 I+600 R = 600 


Edit: Same protocol for your second reaction, with or without Inert, upon the right model selection. 

My understanding 

Good luck.
