Consider a binary system described by a two-constant Margules model. Begin by deriving an expression for RT G. RT da . Recall that 1 dG RT dx 1 d GIM 1 dGEX RT da RT dx + For each set of values for A and B, determine whether LLE exists by plotting dG/dx vs x. If LLE exists, calculate the composition of the two phases using Python. (a) A/RT=3.1239 and B/RT = 0.6672. (b) A/RT=2.1185 and B/RT = -0.0456. (c) A/RT = 1.0217 and B/RT = 1.0134. Note that you can solve this problem without ever specifying RT.
