Endergonic and Exergonic Reactions Reactions that have a negative ∆G and, consequently, release free energy, are called exergonic reactions. Exergonic means energy is exiting the system. These reactions are also referred to as spontaneous reactions because they can occur without the addition of energy into the system. When can reactionsRead More →

A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. A roaring bonfire is an example of a spontaneous reaction, since it is exothermic (there is a decrease in the energy of the system as energy is released toRead More →

In an endothermic reaction, energy is absorbed during the reaction, and the products thus have a larger quantity of energy than the reactants. … Therefore, the reaction would not occur without some outside influence such as persistent heating. However, endothermic reactions do occur spontaneously, or naturally. Are exothermic reactions spontaneousRead More →

Explanation: Entropy ( S ) is a measure of the disorder in a system. In a closed system, entropy always increases over time. … If entropy (disorder) increases, and the reaction enthalpy is exothermic ( ΔH0 & small), the reaction is generally spontaneous. Do non spontaneous Reactions increase entropy? IfRead More →

It is active transport: the solute is being transported against its concentration gradient which requires energy. Many spontaneous reactions occur very slowly. … If the spontaneous reaction has a high activation energy that is rarely attained, the rate of the reaction may be low. Is a spontaneous reaction Rapid? SpontaneousRead More →

The most common cause of inexplicable cracks in windows is stress. Stress cracks—also referred to as thermal stress cracks—can occur in windows when a thermal gradient causes the glass in your window to expand by different amounts in different parts of the window. Can glass just crack on its own?Read More →
