For a spontaneous process DeltaS("surr")...

For a spontaneous process `DeltaS_("surr")=+10J*K^(-1)`. What will be the value of `DeltaS_("sys")` ?

Text Solution

Verified by Experts

Under a given condition, a process will be spontaneous if
`DeltaS_("univ") gt0` i.e., `DeltaS_("sys")+DeltaS_("surr")gt0`. So, `DeltaS_("sys")gt-DeltaS_("surr")`
Given: `DeltaS_("surr")=+10J*K^(-1)`. So, `DeltaS_("sys")-10J*K^(-1)`.
