Reactants in an equation
WebThe direction in which we write a chemical reaction (and thus which components are considered reactants and which are products) is arbitrary.

WebJan 16, 2024 · Chemical reactions must be balanced or, in other words, must have the same number of various atoms in the products as in the reactants. Balancing Chemical Equations Examples Example 1: Balance... WebThe equation you gave (Hproducts - Hreactants) is also a valid equation, but the interpretation of delta H would just be the opposite of what was described above. Using your equation, a negative delta H would indicate an endothermic reaction and a positive delta H would indicate an exothermic reaction. Same concept, different interpretation.
WebAboutTranscript. An elementary reaction is a reaction that occurs in a single step. The rate law for an elementary reaction can be derived from the coefficients of the reactants in the balanced equation. For example, the rate law for the elementary reaction 2A + B → products is rate = k[A]² [B]. Created by Jay.
