you don't solve for a, a is a value that's given in a table...
you just find it in your text book or somethng,
it gives you the value of a for the specific real gas you're working with.
The partial derivative of the van der Waals equation with respect to volume is the derivative of the equation with respect to volume while keeping other variables constant.
In short just use algebra to get the equation below Start with [P + a*(n/V)^2] * (V - nb) = nRT which is the standard Van Der Waals equation and solve for n using algebra. which gives the 3rd order equation below. -(ab/V^2)*n^3 + (a/V)*n^2 - (bP+RT)*n + PV = 0 The simplest way to solve this equation is to enter it into Excel and graph it with multible values of n from 0 to whatever gets you to zero. The value that gives you zero is the answer. Be sure you use all the proper units for the other varables. Hope this helps.
First, calculate the van der Waals constants (a and b) for Cl2. Then, substitute these values, along with the given values (n = 1.000 mol, V = 22.41 L, and T = 273 K), into the van der Waals equation to find the pressure. Finally, compare the calculated pressure with that predicted by the ideal gas equation (PV = nRT) for the same conditions.
Jac van der Waals is known for his work in physics, particularly for his development of the Van der Waals equation of state that describes the behavior of gases and liquids. His research laid the foundation for the study of intermolecular forces.
The Nobel Prize in Physics 1910 was awarded to Johannes Diderik van der Waals for his work on the equation of state for gases and liquids.
i dont know but still you are not answering me.why?
The van der Waals constants a and b are used to correct for the attractive forces between gas molecules (a) and the volume occupied by the gas molecules (b) in the van der Waals equation, which provides a more accurate description of gas behavior compared to the ideal gas law.
Johannes Diderik van der Waals was born on November 23, 1837.

They are named after Johannes Diderik van der Waals who was the first to postulate about inter molecular forces
Hydrogen bonds are the reason for cohesion and Van Der Waals equation is the cause of adhesion.
Johannes Diderik van der Waals died on March 8, 1923 at the age of 85.
