Kp - equlibrium constant

What is partial pressure?

Each gas's contribution to the total
pressure

How would you calculate
the partial pressure of a
gas?

Partial pressure p = mole fraction x total pressure

What is the mole fraction?

Mole fraction of gas X = number of moles of gas X in the
mixture ➗ total number of moles of gas in the mixture

A reaction is represented by
aA (g) + bB (g) ⇌ cC (g) +
dD (g)

what Kp for the
system?

How do you calculate the
units for Kp?

Write out the units for the partial pressures in the
same arrangement as the Kp equation and
cancel out/multiply together.
Usually in Pa

What is the effect of
increasing temperature on
Kp for an endothermic
reaction?

Equilibrium shifts to the right

What is the effect of
increasing the overall
pressure on Kp for this
reaction?

Pressure does not affect Kp as

What will be the kinetic
effect of increasing the
temperature and pressure
for any reaction?

Increasing both will increase the rate of reaction as:
Temperature - many more particles have energy greater than
or equal to the activation energy → more successful collisions
per second
Pressure - more particles in the same volume → more
successful collisions per second.
