Problem Number 1 ( First Order Reversible Reaction )

[@RavySpace]

Thanks alot for the explanation, but maybe someone could explain. If it is in a batch reactor probably:
CAo + CBo = CA + CB
But how it can be,
CB = (CAo + CBo)/2 - CA
instead of that, Is it possible to use this one below?
CB = (CAo + CBo) - CA
