Reaction Kinetics, batch reactor varying volume

NO TEMPLATE BECAUSE THREAD WAS ORIGINALLY ENTERED INTO WRONG FORUM

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?
