Question
really stuck on these questions i dont have any time conversation data I'd really appreciate a clear step by step on how the answer is reached. thank you
![A company is looking to analyse the performance of a PFR, and would like to know which
method is quick and relatively accurate. A homogeneous gas reaction takes place in a PFR
in the presence of 1 mole of an inert molecule, with the following scheme:
A → 3R
At 215 °C it has been reported to have a reaction rate, and rate constant:
K = 1 x 10-² [S-1]
(-A) = KC⁰.5 [mol / litre second]
You are tasked with finding the space time needed for a 80% conversion within this plug flow
reactor operating at 215°C and 5 atm pressure when CA, = 0.0625 mol/litre.
You need to demonstrate
1. A graphical approach to your solution.
a. Plot a graph and estimate the space time.
2. A numerical approach to your solution
a. Plot a graph and use an approximation method to solve for space time
3. An analytical approach to your solution.
a. Solve the integration directly to solve for space time](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff4ce285f-0e45-474f-8d31-62d81d91fa62%2Fa1690c12-5586-4505-9948-6d733225ee37%2Fm0dhnh6_processed.png&w=3840&q=75)
