Pure msg, a common flavor enhancer, exhibits a specific rotation of +24. calculate the ee of a solution whose [α] is +11.

The ee is the short term for enantiomeric excess. The formula for this is given as:

ee = [α] mixture / [α] pure enantiomer

Thus substituting the given values:

ee = + 11 / + 24

ee = 0.4583 = 45.83%

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
