PLEASE HELP!! Consider an adiabatic constant pressure batch reactor for the following ideal gas phase reaction: 2. A—В+С The reactor initial composition is of 50 mol% A and 50 mol% inert material. The initial reactor temperature is 300 K and the pressure is 101.325 kPa. The reaction rate is: -2,500 (-) kCwhere k=exp| Т The enthalpy of reaction can be assumed constant at -5,000 J/mol.

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.

QUESTION 1: 20 marks 20 points It is planned to carry out the following second-order, elementary, non- catalytic gas-phase reaction in an adiabatic CSTR: A+B_C+3D. Only A and B (no inerts) are fed to the reactor at equimolar flow rates of 150 mol/min each. The rate constant is related to the temperature by Arrhenius law as follows: k = 37.68x10^10 exp(-80000/RT) L/mol.min. The heats of formation of A, B, C and D (at 298 K) in kJ/mol are -235.3, -393.5,...
The production of methyl bromide is an irreversible liquid-phase reaction that follows an elementary rate law. The reaction CNBr (A) + CH3NH2 (B)àCH3Br (C) + NCNH2 (D) is carried out isothermally in a semi-batch reactor. A solution of methylamine (B) in extra dry ethanol at a concentration of 0.025 mol/L is to be fed at a rate of 0.05 L/s to an solution of bromine cyanide (A) in extra dry ethanol contained in a glass-lined reactor.
