Question 4 Reactant A enters the reactor at volumetric flow rate of 10 dm /min. The system is operated at 27C and 4 atm. Reactant A decomposes by three simultaneous reactions to form three products in three gas-phase reactions shown below AX Reaction 1 AB Reaction 2 AY Reaction 3 Bis the desired product and the gas constant is 0.082 dm atm K.mol. The reaction rate and activation energy are shown in Table 05.
