Solve Exercise 4.2 in the image below:

F Exercise 4.1: Order versus rate of reaction Liquid A decomposes with nth-order kinetics in a batch reactor A- B, r = kca OS The conversion of A reaches 50% in a five-minute run. What is the order of the reaction if it takes 10 minutes to reach 75% conversion? What is the order of the reaction if it takes 20 minutes to reach 75% conversion? What is the order of the reaction if it takes 30 minutes to reach 75% conversion? Exercise 4.2: Constant volume versus constant pressure batch reactor Consider the following two well-mixed, isothermal gas-phase batch reactors for the elementary and irreversible decomposition of A to B, Ak 2B IS101 reactor 1: The reactor volume is held constant (reactor pressure therefore changes). reactor 2: The reactor pressure is held constant (reactor volume therefore changes). Both reactors are charged with pure A at 1.0 atm and k = 0.35 min-1. (a) What is the fractional decrease in the concentration of A in reactors 1 and 2 after five minutes? (b) What is the total molar conversion of A in reactors 1 and 2 after five minutes
