`1` mol of an idel gas is allowed to expand isothermally at `27^(@)C` till its volume is tripped. If the expansion is carried out reversibly then select the correct option(s) : `(R = (25)/(3)(J)/("molK"),log3=0.48)`

Text Solution

Verified by Experts

The correct Answer is:
0

In isothermal revbersible process.
`DeltaS=(q_("rev"))/(T)`
`q=-w=2.303 RT "log" (V_(2))/(V_(1)) = 2740.6 J//"mole"`
`DeltaS_("surr")= (q_("rev"))/(T) = (2740.6)/(300) =9.135 J//K "mole"`
`DeltaS_("surr") = -DeltaS_("system") =- 9.135 JK^(-1) "mole"^(-1)`
`DeltaS_("universe") = 0`
