Calculate the S(univ) for the following phase change at 25 deg celcius. The boiling point of heptane is 98.0 Celcius and has a Delta Hvap= +21.6kj/mol.
C7H16(l)--> C7H16(g) Delta S= +79.0j/k
I know that the equation is
Delta Suniv= DSsys + DSsurr
PLEASE SOMEONE HELP ME WITH THIS PROBLEM, I CANT FIGURE IT OUT!!!
All I know is Delta Ssys= +79.0
