Select the true statements about endergonic reactions. The products have higher free energy than the reactants. Endergonic reactions have a positive change in free energy. Endergonic reactions are not spontaneous.Click to see full answer. Furthermore, which statement is true about exergonic reactions?There is a positive ΔG. Energy is released from the reactants. The products of exergonic reactions have more free energy than the reactants.Beside above, what is the definition of an endergonic reaction quizlet? a reaction in which the products have more energy than the reactants. Plants use sunlight to convert carbon dioxide and water into sugar and oxygen. The energy in the sunlight is what type of energy? Consequently, which statement about chemical reactions is true? A chemical change can take place rapidly, slowly or too slowly. For example, rusting of iron is a slow chemical change. Therefore, the statement which is true about a chemical reaction is that it occurs whenever a chemical change takes place.What happens in an endergonic reaction?In chemical thermodynamics, an endergonic reaction (also called a heat absorb nonspontaneous reaction or an unfavorable reaction) is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed. For an overall gain in the net result see exergonic reaction.
