Energy Balance for Multiple Reactions in Plug-Flow Reactors

1 Energy Balance for Multiple Reactions in Plug-Flow Reactors 

When we have multiple reactions occurring, we have to account for the heat of reaction in each reaction. For q multiple reaction.s taking place in the PFR where there are m specie.s, it is easily. shown that Equation (12-5) can be generalized to 

1 = Reaction number The heat of reaction for reaction i must be referenced to the same species in the i = Species jjy which is multiplied, that is. 

Joules released in reaction i Moles of j reacted in reaction i
