Homework Help: Reaction Kinetics, batch reactor varying volume

  1. Apr 30, 2016 #1

    Hi Guys,

    I have attached the question that I am struggling with (part b of the question)

    I have worked out that the conversion of A is X=0.21

    Using this conversion I'm trying to work out the time required for the reaction

    I am trying to use this equation: dCa/dt=Ra
    where Ra is the reaction rate
    but if i integrate the reaction rate i can't assume its constant due to volume and concentration changes so I'm in a bit of a dilemma.

    Can you guys let me know if my reasoning is wrong, or if Ra is constant

    What is the total molar density in the reactor? Does this change as the reaction proceeds?
