An elementary irreversible gas-phase reaction, A → B + C, is carried out at fixed temperature and pressure in two separate ideal reactors: (i) a 10 m plug flow reactor (PFR), (ii) a 10 m3 continuous-stirred tank reactor (CSTR). If pure A is fed at 5 m3 h-1 to the PFR operating at 400 K, the conversion is 80%. If a mixture of 50 mol% of A and 50 mol% of an inert is fed at 5 m³ h-1 to the CSTR operating at 425 K, the conversion is 80%. The universal gas constant R = 8.314 J mol-1 K-1. Assuming the Arrhenius rate law, the estimated activation energy is kJ mol-1 (rounded off to one decimal place).

gas phase reactionA -> B + Ccarried out isothermally in a constant volume batch reactor of 100 L. An amount of 100 moles of pure A is initially placed in the reactor. The reactor is well mixed and the ideal gas equation holds. If the reaction is first order,-rA = kCA with k = 1 1/sCalculate the time required to consume 80% (moles) of A.

In a batch reactor, a substance A was processed, which generated different products (D and U), through competitive parallel reactions with the following reaction kinetics: After 20 minutes of reaction, it was determined that the composition of the reaction medium was CA = 1 mol/L, CD = 5 mol/L, CU = 2 mol/L. The option that indicates, respectively, the instantaneous and global selectivities at the end of the reaction are: A) 3 and 2. B) 2.5 and 2. C) 2 and 3. D) 2 and 2.5.
