2. The second order gas phase isomerization 2A + B +C is to be carried out at constant temperature in a packed bed reactor (PBR). The specific reaction rate at is 102 dm/(mol.kg.s). Pure A enters the reactor at 10 atm and 127 C with a molar flow rate of 2.5 mol/s. If the pressure drop parameter for the isotherma PBR, a is 0.02 kg1, determine the catalyst weight needed to achieve 90% conversion
