`SO_(2(g))+(I)/(2)O_(2(g))rarrSO_(3(g))`

Text Solution

Verified by Experts

Calculate work done in the following reaction :
`SO_(2(g))+(1)/(2)O_(2(g)) rarr SO_(3(g))`
`Delta n=n_(2)-n_(1)`
`=1-(1+(1)/(2))=-(1)/(2)`
`E=Delta nRT`
`=-(-(1)/(2))xx8.314 xx323`
`=+1343J or 1.343kJ`
Since W is positive , work is done on the system by the surroundings.
