Answer question 2 &3
1) (30 points) Using the diagram below, answer the three questions below: Which pair of compounds is totally miscible? Water/L-Val Water/L NVA LNVA/L-Va Which pair of compounds is partially miscible? Water/L-Val a/L NVA L-NVA-Val Which pair of compounds is nearly immiscible? Water/L-Val Water/L-NVA L-NVA/L-Val aid 2) (5 points each) Which activity coefficient model(s) have constants that can change with temperature Fig. 13.Val poriication strps us ines repvesent water Wilson Two-parameterVan Laar Margules Margules 3) (10 points) Which activity coefficient model generally works for predicting SLE? Wilson Margules Margules 4) (10 points) What type of model have we assumed when we write f-yap? Ideal gas modely Ideal solution model Real solution model 5) (10 points) What type of model have we assumed when we write0 P? Ideal gas model Ideal solution model Real solution model 6) (10 points) What type of model have we assumed when we write fxy Pst Ideal gas model Ideal solution model Real solution model 7.(10 poimty) What is he lowest temperature point on an SLE diagram called? E steic pointExplanation / Answer
1. L-valine (L-Val)/L-norvaline are completely miscible
water and L-valine is partially miscible (solubility 85 g/l)
water and L-NAV are nearly miscible
2.wilson modle have constants that change with temperature
3. WILSON MODEL WORKS FOR PREDICITING SLE
