To determine whether a chemical reaction is spontaneous we must calculate the change in total entropy of the chemical system and its surroundings. This can be done directly using Î´ S Â° sys and âÎ´HÂ°/ T or indirectly using the change in Gibbs free energy Î´ G Â°.
Infield shift. The infield shift is a generic term used in baseball to describe an extreme defensive realignment from the standard positions to blanket one side of the field or another.
