I don't know where to start using the polymath software... The question requires I solve it using polymath

 

The question is:

 

The gas-phase dehydration of butanol is carried out over a silica-alumina catalyst at 680K. 

The rate law is:  -r'_butanol= k₁P_butanol/(1+k₂P_butanol)²

With k₁ = 0.075 mol gcat^-1 hr^-1 atm^-1 and k₂ = 0.45 atm^-1. Pure butanol enters a thin tube packed bed reactor at a molar flow rate of 50 kmol hr^-1 and a pressure of 10 atm.

a) Using Polymath software calculate the PBR catalyst weight necessary to achieve 85% conversion in the absence of pressure drop?

 

 

Thanks if anyone can help at all!!
