Answer:

W = 350.6 J

Explanation:

Given that,

The volume decreases from 5.20 to 1.13 L against a constant pressure of 0.852 atm.

The change in volume = 1.13 L - 5.20 L = -4.07 L

Work done, W = - PΔV

So,

W = 0.852 atm Ă— -4.07 L

= - 3.46 L-atm

or

[tex]W=3.46\ L-atm\times \dfrac{101.33\ J}{1\ L-atm}\\\\=350.6\ J[/tex]

So, the required work done is 350.6 J.
