Endothermic Reactions

Endothermic Reactions. In nuclear and particle physics the energetics of nuclear reactions is determined by the Q-value of that reaction. The Q-value of the reaction is defined as the difference between the sum of the masses of the initial reactants and the sum of the masses of the final products, in energy units (usually in MeV).. Consider a typical reaction, in which the projectile a and the

Exothermic Reaction Examples Found in Real Life

Exothermic vs. Endothermic Reactions. It can be easy to mix up exothermic and endothermic reactions. But they are actually opposites: while exothermic reactions create heat and light, endothermic reactions require heat or light to occur. Examples of endothermic reactions include photosynthesis (which uses sunlight) and melting ice cubes (which

Can dissolution reactions be endothermic?

Regarding why the substance is soluble why its dissolution is endothermic, you have to remember that the reaction takes place if Δ r G is favourable (i.e. negative), and Δ r G = Δ r H − T Δ r S. Overall the free energy must be negative for dissolution to occur (on a thermodynamic basis; kinetics are another issue), not the enthalpy. Share.

C3.3 Calculating and explaining energy change

Endothermic reaction: A chemical reaction that absorbs heat from its surroundings. The energy of the products is more than the energy of the reactants. The energy needed to break existing bonds is greater than the energy released from forming new bonds. The overall heat energy change for the chemical reaction, ΔH is, shown as a +ve value.
