4 In the prior problem set we used the regular solution model to show that oil and water do not mix unless the solution is very dilute. But regular solution theory is not the best model to use for such a calculation because oil and water do not have similar molecular volume. Here we use Flory-Huggins Polymer theory to explore if oil and water mix. Assume oil is a hydrocarbon polymer for which N=10 and water is the solvent. For hydrocarbon-water mixtures assume wSP=5 and T=300K. Assume the volume fraction of oil is φoil=0.3. a. Calculate ΔS¯MIX . b. Calculate \(\Delta \bar{H}_{MIX)\) assuming the same conditions as part A. c. Calculate ΔG¯MIX assuming the same conditions as part A.
