For the reaction, `N_(2)O_(5)(g)=2" NO"_(2)(g)+0.5" O"_(2)(g)`, calculate the mole fraction of `N_(2)O_(5)(g)` decomposed at a constant volume and temperature, if the initial pressure is 600 mm Hg and the pressure at any time is 960 mm Hg. Assume ideal gas behaviour.

Text Solution

Verified by Experts

Suppose initial pressure of `N_(2)O_(5)` is P mm and decrease is pressure of `N_(2)O_(5)` in time t is p mm.
`"Then "N_(2)O_(5)(g)=2" NO"_(2)(g)+0.5" O"_(2)(g)`
`"Initial "P" mm"`
`{:("After time t,",,,(P-p),,,2p,,,0.5p,,,"Total"=P+1.5p):}`
`P prop 600" mm and "(P+1.5" p")prop 960" mm or "1.5" p "prop 360" mm or "p prop 240" mm"`
Mole fraction of `N_(2)O_(5)` decomposed `=(p)/(P)=(240)/(600)=0.4`
