  • Define total pressure?
    The sum of all pressures of individual gases.
  • How to calculate mole fraction of a gas?
    No. moles of a gas / Total no. moles of gas in mixture.
  • How to calculate partial pressure?
    Mole fraction of a gas x total pressure in mixture
  • Define kp?
    Equilibrium constant for equilibrium reaction involving gases using partial pressure.
  • Kp expression?
    Kp= (PA)a(PB)b / (PC)c(PD)d
  • How does temp affect Kp?
    Kp is only valid for 1 temp as changing temp changes equilbrium pressures, changing Kp.
  • What happens to Kp when we increase temp of an exothermic forward reaction?
    It decreases as equilibrium shifts in endothermic reaction.
  • How does pressure affect kp?
    No effect on Kp
  • How does a catalyst affect Kp?
    No affect on Kp value.
    Catalyst speeds up forward/reverse reaction and rate
  • What is partial pressure?
    each gases contribution to the total pressure
  • how would you calculate pp of a gas?
    mole fraction x total pressure
  • What is mole fraction?
    no. of moles of gas x in mixture / total no. moles of gas in mixture
