L-Serine is an amino acid important for its roles in synthesizing other amino acids and for its use in intravenous feeding solutions. It is often synthesized commercially by fermentation, and recovered by subjecting the fermentation broth to several processing steps and then crystallizing the serine from an aqueous solution. The solubilities of L-serine (L-Ser) in water have been measured at several temperatures, producing the following data:5T(K) 283.4 285.9 289.3 299.1 316.0 317.8 322.9 327.1x(mole fraction L-Ser) 0.0400 0.0426 0.0523 0.0702 0.1091 0.1144 0.1181 0.1248One of the ways such data can be represented is with the van’t Hoff equation: ln x =( a=T b).Graph the data so that the resulting plot is linear. Estimate a and b and give their units.
