Can you help me please for this chemistry question ?

a) Add CO ) Add a catalyst 5. (15pt) The fgure shows a two-chamb ws a two-chambered system with a movable piston. Chamber A (For methane, a 2.25 L2 atm mol Chamber B ha Calculate the work done by the methane gas if it neglect any change in Pressure during expansion) Work done by methane has a volume of 2L. It contains 1 mol of methane gas at 273 K. 2, b-0 0428 L mol ') s a volume of 2L. It contains 1 mol of an ideal gas at 273 K expands to 2.5 L. (Please A Mt

Explanation / Answer

A.

Using van der Waals equaiton,

(P + an2/v2) (V-nb) = nRT

(P + 2.25 / 22)(2 - 1* 0.0428) = 1 * 0.0821 * 273

P = Pressure = 10.9 atm

NOW,

Work done = Pext * (V2 - V1)

W = 10.9 * (2.5 - 2.0)

W = 5.44 L.atm

W = 5.44 * 101.325 J

W = 551.7 J
