Question

A 10 litre flash containing a gaseous mixture of co and CO2 at a total pressure of 2.0 bar if 0.20 mole of CO is present, find its partial pressure and also that of CO2​

Answer 1

$\huge{ \tt{ \underline{ \underline{ \blue{sᴏlᴜᴛɪᴏɴ :}}}}}$

$\tt{➨ Total \: moles = \frac{RT}{PV}}$

$\tt{➨ \frac{2×10}{298 × 0.0821}}$

$\tt{➨ \: 0.8174}$

$\tt{➨ Moles \: of \: CO2}$

$\tt{➨ \: 0.8174 \: − \: 0.2}$

$\tt{➨ \: 0.6174}$

$\tt{➨ Partial \: pressure \: of \: CO= XCO × 2}$

$\tt{➨ \: \frac{0.2}{0.8174 }× 2}$

$\tt{➨ \: 0.4893 \: atm}$

$\tt{➨ Partial \: pressure \: of \: CO2}$

$\tt{➨ \: 2 \: − \: 0.4893}$

$\tt{➨ \: 1.51 \: atm}$
