van der waals equation meaning of each term
Van der Waals equation where Vm is the molar volume of the gas, R is the universal gas constant, T is temperature, P is pressure, and V is volume. When the molar volume Vm is large, b becomes negligible in comparison with Vm, a/Vm2 becomes negligible with respect to P, and the van der Waals equation reduces to the ideal gas law, PVm=RT.[6]
Chemical equation A chemical equation consists of the chemical formulas of the reactants (the starting substances) and the chemical formula of the products (substances formed in the chemical reaction). The two are separated by an arrow symbol (  →  {\displaystyle \rightarrow } , usually read as "yields") and each individual substance's chemical formula is separated from others by a plus sign.
