The melting points of canola oil, corn oil, sunflower oil, and peanut oil are 10°c, –11°c, –17°c, and –2°c. if you cool a mixture of these oils to 5°c, which one can you separate easily?

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.
