How do you find the partial pressure of reactants and products when you are given Kp and an initial molarity?
Thank you :~)

Re: Calculating partial pressure using concentration
Normally for these kinds of problems you are also given temperature. With this information PV=nRT can be readjusted to P=cRT (since concentration=n/V). Now you can find the partial pressure of that molecule and use the formula for Kp to find the partial pressure of another reactant or product. I hope this helps.

Re: Calculating partial pressure using concentration
You use the conversion formula Kp=Kc(RT)^delta n where R is the universal gas constant 0.08206 with its unit of (L*atm)/ (mol*K).

You don't have to set up an ICE table. Use PV=nRT, and then P=conc(RT).
