If a reaction is product-favored on the basis of enthalpy and reactant-favored on the basis of entropy, then it most likely is ____ and ____ net moles of gas.

Question

Quizplus · Accepted Answer

If a reaction is product-favored on the basis of enthalpy, it is exothermic, releasing heat as a product. If it is reactant-favored on the basis of entropy, it means that the products have a greater degree of disorder than the reactants, and in general, this implies that the reaction produces more moles of gas than it consumes. The only option with these two characteristics is B: exothermic and consumes net moles of gas.
