Check the option(s) in which a chemical reaction is spontaneous (AS univ> 0) only below a certain temperature. There is an increase in entropy from reactants to products, and there is no heat exchange with the surroundings and thus no entropy change in the surroundings. There is a decrease in entropy from reactants to products, but the reaction releases lots of heat to the surroundings, raising the entropy of the surrounding. There is a decrease in entropy from reactants to products, and the reaction absorbs heat from the surroundings, lowering the entropy of the surrounding particles. There is an increase in entropy from reactants to products, but the reaction absorbs heat from the surroundings, lowering the entropy of the surrounding particles. There is an increase in entropy from reactants to products, and the reaction heats up the surroundings.

A chemical engineer is studying the two reactions shown in the table below. In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 69.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium.

A chlorine (CI) and bromine (Br) atom are adsorbed on a small patch of surface (see sketch at right). This patch is known to contain 36 possible adsorption sites. The Cl and bromine (Br) atoms have enough energy to move from site to site, so they could be on any two of them. Suppose the Br atom desorbs from the surface and drifts away. Calculate the change in entropy. One way a Cl and Br atom might be adsorbed on a Round your answer to 2 significant digits, and be sure it has the correct unit symbol. surface with 16 sites. Ox10 ?
