we still see we have products over reactants
the only thing that differs, is that instead of having we still see we have products over reactants
the only thing that differs, is that instead of having
the concentration of C, we have the pressure of C. the only thing that differs, is that instead of having

Likewise we have the concentrations of A and B
and the pressures of A and B. Likewise we have the concentrations of A and B
and the pressures of A and B.
Note also, that we have a
p as a subscript for Kp
and c as a subscript
this distinguishes on K value from the other
because they will have different numerical values.
There is a way to derive the mathematic relationship between these two values
using the ideal gas law, but we are not going to show that here There is a way to derive the mathematic relationship between these two values

the equilibrium constant with respect to pressure

times RT to the delta n.
Note: that RT is in parentheses times RT to the delta n.
Note: that RT is in parentheses
and so that delta n goes with
everything inside those parentheses and so that delta n goes with

R is our ideal gas constant
0.08206 liters-atmospheres per mole kelvin. R is our ideal gas constant
0.08206 liters-atmospheres per mole kelvin.
And our temperature, as usual, must be in unit of kelvin. 0.08206 liters-atmospheres per mole kelvin.
