please show all work

1. An isothermal packed bed reactor is used for the following gas phase reaction: A + B2C TA' = -2 CACB a. (8 pts) Please derive the design equation in terms of extent of reaction, pressure, catalyst weight, constants, and inlet feed specifications only. b. (5 pts) Please derive the Ergun equation for pressure drop in terms of pressure, catalyst weight, extent of reaction (if necessary), constants, and inlet feed specifications only
