Question

1. Gas Benzene, CH memiliki temperatur 510°C dan tekanan 5,9 MPa. Cari nilai Z! Apakah benzene pada kondisi ini merupakan gas ideal atau tidak? Berikan juga alasannya

Gas Benzene, C6H6 memiliki temperatur 510 °C dan tekanan 5,9 MPa. Cari nilai Z! Apakah benzene pada kondisi ini merupakan gas ideal atau tidak ? Berikan juga alasannya

Answer 1

Given T = 510$\degree$C=510+273= 783K

P = 5.9 Mpa

use property table shown below to find Tcr and Pcr for benzene

Tcr = 562K

Pcr = 4.92 Mpa

Then find reduced Temperature(Tr) and reduced pressure (Pr)

Tr = T/ Tcr

Tr =  783/ 562

Tr= 1.39

Pr = P/ Pcr

Pr =5.9/4.92

Pr = 1.2

Using Tr and Pr find Z value from Generslised compressibility chart

we get Z= 0.88 approximately

ideal gas law considering xompressibility

PV= ZRT

Z=1 for ideal gas

but we got Z=0.88 < 1 so the given gas is not ideal gas BUKAN GAS YANG IDEAL KARENA Z KURANG DARI 1
