Calculate the reaction energy q

WebThis is called an endothermic reaction. If heat flows from the system to the surroundings, the reaction gave off energy. Therefore the change in enthalpy for the reaction is negative and this is called an exothermic reaction. As an example of a reaction, let's look at the decomposition of hydrogen peroxide to form liquid water and oxygen gas. WebQ = Tfinal – Tinitial = Tb + TB – (Ta + TA) For reactions in which there is an increase in the kinetic energy of the products, Q is positive. The positive Q reactions are said to be …

WebQ Values The Qvalue of a nuclear reaction is 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). This is also the corresponding difference of the binding energies of the nuclei (not per nucleon), since nucleon number is conserved in a reaction.
