Answer:

43.1atm is the pressure using gas law and 27.2atm using Van der Waals Law.

Explanation:

Ideal gas law is:

PV = nRT

Where P is pressure in atm

V is volume = 4.00L

n are moles of the gas (For chlorine Molar Mass: 70.90g/mol):

500g * (1mol / 70.90g) = 7.052 moles

R is gas constant = 0.082atmL/molK

T is absolute temperature = 25°C + 273 = 298K

To solve the pressure, P:

P = nRT/V

P = 7.052mol*0.082atmL/molK*298K / 4.00L

P = 43.1atm is the pressure using gas law.

Van der Waals equation is:

$P + a(\frac{n}{V})^2 * (V-nb) = nRT$

Where a is 6.58L²atm*mol⁻²

b = 0.056Lmol⁻²

Solving for pressure:

$P + a(\frac{n}{V})^2 = \frac{nRT}{(V-nb)}$

$P = \frac{nRT}{(V-nb)}-a(\frac{n}{V})^2$

$P = \frac{7.052mol*0.082atmL/molK*298K}{(4.00L-7.052mol*0.056L*mol)}-6.58L^2mol^{-2}(\frac{7.052mol}{4.00L})^2$

P = 172.323 / 3.6051 - 20.4866

P = 27.2atm using Van der Waals Law

The relationship between the answers to parts (d) and (e) is given that the system doesn't have constant pressure, ΔH(enthalpy change) and Q(heat transferred) can be stated to be equal to one another.

A thermodynamic system's enthalpy, which is one of its properties, is calculated by adding the system's internal energy to the product of its pressure and volume. It is a state function that is frequently employed in measurements of chemical, biological, and physical systems at constant pressure, which the sizable surrounding environment conveniently provides.

Q (Heat) is referred to as energy in motion. On the other hand, enthalpy (ΔH) represents the system's condition and total heat content. The change in internal energy is equal to the heat transmitted to, less the work done by, the system, according to the law of energy conservation. The enthalpy change(ΔH) is precisely equal to the heat transferred(Q) to the system if the sole work performed is a change in volume at constant pressure.
