The pressure of real gases is less than that of ideal gas because of

Step-by-step solution

The force of attraction in real gases tend to show slightly lower pressure as compared to ideal gasses. ( p_ ideal =p_ real + a n² V² ) or ( p_ real =p_ ideal - a n² V² ) where ' ( a ) ' is the constant which measure the magnitude of attractive forces among the molecules of gas ' ( n ) ' is the no. of moles present and ' ( V^ ) is the volume of gas present.
