please answer a and b

1. The irreversible first-order gas phase reaction: is carried out in a PBR. Because the reactor is isothermal and total moles don't change, the pressure gradient along the length of the packed bed is approximated as constant: dP -0.3 atm/kg dW Another way of saying this is yo = 0.3 atm/kg. The feed pressure is 20 atm and the catalyst weight in the packed bed is 50 kg. The rate constant k is 0.00956 min-'. Initial molar flow of A is 0.241 mol/min with a feed volumetric flow rate of 0.1 L/min. The void fraction is 0.45 and the catalyst density is 4 kg/L. a. What is k? b. What is the conversion of A
