How to Solve Reactor Design Problems

[@sapphire8881]

Does rate of reaction rb = +2kCa^2 @7:27 ?

[@steverajesh4981]

But my college teacher teaching ,A->2B,rate of disappearance becomes -rA=kCA^1,rate of appearance becomes rA=kCB^2

[@smokenf92]

I'm guessing this was not revised and never will lol
