A spontaneous process has DeltaS("sys")=...

A spontaneous process has `DeltaS_("sys")=xJ*K^(-1) and DeltaS_("surr") =-yJ*K^(-1)`. Compare the values of x and y.

Text Solution

Verified by Experts

For a spontaneous process, `DeltaS_("univ")=DeltaS_("sys")+DeltaS_("surr")gt0`
Now, `DeltaS_("sys")=xJ*K^(-1) and DeltaS_("surr")=-yJ*K^(-1)`
`therefore (x-y)J*K^(-1)gt0` or, `x gt y`
Hence, value of x is greater than the value of y.
