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
