A synthesis reaction is one in which two or more substances are combined to form a more complex one. D H 0 D S 0. Some mass and energy are lost in a nuclear reaction.

That means the reaction is endothermic. This occurs when the levels were less than 035. The heat of formation of the elements are always zero whether they are molecules or atoms.

The reaction order of a chemical reaction is always defined with the help of reactant concentrations and not with product concentrations. Thus D S univ 0 and D G 0. Mass and energy are produced in a nuclear reaction.

The value of the order of reaction can be in the form of an integer or a fraction. That means the reaction is exothermic.
