"2 moles of X was heated to a temperature of 2000°C until equilibrium was established under a total pressure of 8 x 10^7 Nm^-2. At equilibrium, X was found tohave undergone 20% dissociation. Calculate Kp.
X(g) +Y(g) + 2 Z(g)"
I have attempted this question but I think I may have gotten the calculating the moles at equilibrium part incorrect because the 20% dissociation confused me a bit.
Can anyone explain how I could do this correctly? Much appreciated.
