In the isothermal reversible compression of 52.0 mmol of a perfect gas at 260 K, the volume of gas is reduced from 300 cm3 to 100 cm3 , calculate w for this process

Respuesta :

Answer:

The work done is 123.5 J

Explanation:

Given that:-

Temperature = 260 K

The expression for the work done is:

[tex]W=-nRT \ln \left( \dfrac{V_2}{V_1} \right)[/tex]

Where,  

n is the number of moles = 52.0 mmol = [tex]52.0\times 10^{-3}\ moles[/tex]

W is the amount of work done by the gas

R is Gas constant having value = 8.314 J / K mol  

T is the temperature  

V₁ is the initial volume  = 300 cm³

V₂ is the final volume  = 100 cm³

Applying in the equation as:

[tex]W=-52.0\times 10^{-3}\ moles\times 8.314\ J/Kmol\times 260\ K \ln \left( \dfrac{100\ cm^3}{300\ cm^3} \right)[/tex]

[tex]W=-52.0\times 10^{-3}\times 8.314\times 260 \ln \left( \dfrac{100}{300} \right)\ J=123.5\ J[/tex]

The work done is 123.5 J
