How do you solve this:

Consider the decomposition of ammonium chloride at a cerain temperature

NH4Cl(s) <- NH3(g) + HCl(g)
->

Calculate the equilibrium constant Kp if the total pressure is 2.2 atm at that temperature.

1. I think I would do the following:
NH4Cl(s) ==> NH3(g) + HCl(g)

Ptotal = PNH3 + PHCl
2.2 atm = PNH3 + PHCl
From the equation, PNH3 = PHCl; therefore,
2.2 = 2PNH3 and you can go from there.
Then substitute partial pressures into
Kp = PNH3*PHCl to find Kp.

2. thank you. so what did you get as a final answer for this problem then? and what did u do after doing 2.2=2PHN3

and after subsituting the partial pressure??

Thanks

3. The remainder of the problem is up to you. We try to HELP you do the work but we don't do it. You can substitute and calculate Kp; it's just multiplying two numbers together.
