Hello,
I am looking at reactions that change volume during the reaction, for example ammonia synthesis
[tex] N_{2} + 3H_{2} \rightleftharpoons 2NH_{3} [/tex]
where it is clear that the products are less moles than the reactants. However, I am thinking of a scenario in a plug flow reactor where this is happening. How can it be that the volume is changing? Aren't the gases just going to occupy the space in the PFR, therefore the volume is constant? Same thing really for a batch reactor too, I mean just because a gas reacts to form less moles, it should still have the volume of its vessel, therefore not change??
