Van der Waal's GAS EQUATION
Instead of PV=nRT for an ideal gas, if an * appears in the formula entry
window, the calculator will substitute the
equation:
(atm+a*moles^2/liters^2)*(liters-moles*b)
= moles*R*degK
where a and b are Van der Waal's gas constants.
You may use any of the units for temperature or pressure and it will
do the conversions necessary. However when you specify the values of
a and b from a table, they must have dimensions consistant with this
equation. See Partial Pressures for some examples.
You can use a combination of ideal and non-ideal gases by setting
a=b=0 for ideal gases.
