DO NOT COPY OTHER CHEGG ANSWERS. I POSTED THIS QUESTION 3 TIMES AND EVERY EXPERT COPIED A WRONG ANSWER. PLEASE ANSWER IT YOURSELF. AND PLEEEEEEASE INCLUDE THE MATLAB PART!!!!!!

A 200dm3 batch reactor is pressurized to 20atm with a mixture of A and B, along with 25% inert. A gas phase reaction A+2B4C is carried out isothermally at 227C. The reaction is third order rA=kCAC2k=0.7dm6/(mol2min) a) Calculate the time necessary to consume 90% of A in a Constant Volume reactor. Plot the reactor Pressure as a function of time. b) how does increasing or decreasing the volume affect the reactor time? c) how do I type the equation in part (a) as a script in matlab
