Kp Equilibrium constant

• Total pressure = sum of partial pressures
• Partial pressure = mole fraction × total pressure
• Mole fraction of A = Number of moles of species A / Total number of moles of all gas species

  Would give a number lower then 0
• Kp

  Equation aA(g) + bB(g) ⇌ cC(g) + d(D)(g)

  Don't use brackets [] because it's not concentration

  Kp = ( P(C)^c × P(D)^d ) ÷ ( P(A)^a × P(B)^b ) with P(A) meaning partial pressure of species A. Units is kPa
• • Temperature affects KP
  • Pressure doesn't affect KP
  • Catalyst has no effect on KP
