(d) use the data in the table below to calculate the value of the standard molar entropy, s° for o2(g) at 25°c standard molar entropy, s ° (j k -1 mol -1 ).
In thermodynamics, these two types of reactions are classified as exothermic or endothermic, respectively an easy way to remember the difference between these two reaction types is by their prefixes: endo- means to draw in, and exo- means to give off. Exothermic reactions are essentially reactions that release energy as heat (in part, at least) to the surroundings, and may cause an explosion or combustion, depending on the amount of heat release. For exothermic reactions, (h is negative, whereas (h is positive for endothermic reactions a negative (h indicates the products are at a lower energy state than the reactants a positive (h indicates the products are at a higher energy state than the reactants. Table of contents 2017 | volume 8, issue 2 and querying of data and content of the open access journal through the online mode thermodynamics & catalysis .
