The second order gas phase irreversible reaction: 2.4-B is carried out in an isothermal batch reactor containing 40 kg of catalyst and with an initial volume of 60-liter. The reactor is initially filled with equal molar quantities of A and inert I at 300 K and 2.5 atm. Calculate the time needed for the concentration of product (B) to be 0.02 mole/liter if: a) the reaction takes in a constant pressure batch reactor (3 points) b) the reaction takes place...

The homogeneous gas reaction 2A ---> 3R follows second-order kinetics. For a feed rate of 4m3/hr of pure A at 5 atm and 350oC, an experimental reactor consisting of a 2.5 cm ID pipe 2 m long gives 65% conversion of feed. A commercial plant is to treat 310 m3/hr of feed consisting of 50% A, 50% inerts at 25 atm and 350 degrees C to obtain 80% conversion. Assume plug flow in the pipe, negligible pressure drop, and ideal...

3. (a) The elementary gas phase reaction: 2A → 3C takes place in a plug flow reactor. The reactor operates isothermally at a temperature of 350 K. The inlet to the reactor is made up from A and inert material. The inlet partial pressures of A and inert material are 10 bar and 20 bar respectively. The rate constant for the reaction is given kr = 1 x 10-6 mmol s1 and the flow rate of incoming A = 2...

Question 10 The gas phase reaction 2A →B + C is carried out isothermally in a 30 dm3 well-mixed constant volume batch reactor. Pure A at an initial amount of 66.3 moles/dm3is placed into the reactor. If the rate of destruction of A is given by –rA = kCA, with k = 0.08 min-1, determine the concentration of A (in moles/dm3) after 5 minutes. Note that concentration is moles divided by volume. Express your answer to one decimal place.

The following first-order gas-phase reaction occurs in an isothermal, isobaric PFR reactor: A->2B. There is 60% A and 40% inert in the initial feed. If the volumetric flow rate at the outlet of the reactor is 1.3 times of the one at entrance, calculate the conversion rate of the reactor. Assume ideal gas law (PQ = NRT)

The reversible gas-phase chemical reaction A reversible 2B takes place in a steady state tubular reactor operated at a constant pressure of 2 atm and temperature of 120 degree C. The forward reaction is first-order, and the backward reaction is second order. We want to process a 100 mole/min stream of pure A. At the operating conditions (120 degree C), equilibrium constant is 0.31 L/mol. What is the equilibrium composition at 120 degree C?
