Question 5 The spontaneity of a reaction depends both on the enthalpy change, Delta H, and entropy change, Delta S. Reactions that release energy produce more stable products, and the universe tends toward disorder. Thus, an exothermic reaction with a positive entropy change will always be spontaneous. Mathematically, this relationship can be represented as where Delta G is the change in Gibbs free energy and T is the Kelvin temperature. If Delta G is negative, then the reaction is spontaneous....

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,...
