The condition of a system at equilibrium represents a
balance between the tendency toward lowest energy (E) and
the tendency toward molecular chaos or maximum entropy (S). The
Gibbs Free Energy, G, is the state function that combines energy
and entropy into an equation that allows us to find the balance
between these two tendencies. For a system undergoing change at
constant temperature, ΔG = ΔH - TΔS. The system stops changing when
it reaches the equilibrium condition, ΔG =...

Chemical energy is released or absorbed from reactions in various forms. The most easily measurable form of energy comes in the form of heat, or enthalpy. The enthalpy of a reaction can be calculated from the heats of formation of the substances involved in the reaction: ΔH∘rxn=ΔH∘f(products)−ΔH∘f(reactants) Entropy change, ΔS∘, is a measure of the number of energetically equivalent microstates introduced into the system during the reaction. The degree of spontaneity of a reaction is represented by the Gibbs free...

A chemical reaction produces very stable molecules from highly reactive molecules. The products are two solids, while the reactants are a liquid and a gas. What type of thermodynamic process is this reaction? Why? Endothermic rxn that is increasing the entropy of the system. Thus, it is a Type 4 reaction O Endothermic rxn that is decreasing the entropy of the system. Thus, it is a Type 2 reaction Exothermic rxn that is increasing the entropy of the system. Thus,...

Entropy of the universe increases in all spontaneous reactions. wo False If entropy is bw enough it con be spontaneous, b. Reactions with a negative free energy change (A-Gº <0) are product-favored and occur with rapid transformation of reactants to products. True c. An exothermic reaction will always be spontaneous.
