Document Summary
A process that occurs by itself under a specific set of conditions. Ex. dropping a book spontaneously in a gravitational level. The direction in which the extent to which a chemical reaction proceeds. Catalysts don"t affect the spontaneity, only speeds up the rate of the reaction. Process that does not occur under a specific set of conditions: unless we provide energy continuously to the system. A process that results in the decrease in the energy of a system often is. The sign of h alone is insufficient to predict spontaneity in every circumstance. H = a factor which helps determine the extent of reaction and spontaneity. T = another factor; changes in t can change direction of spontaneity. Entropy is a property associated with the state of the system o. Entropy is a measure of how spread out or how dispersed the system"s energy is.
