Energy required for chemical reaction
WebThe energy required to end a chemical reaction The energy required to form the bonds in the product molecules The energy required to break the bonds of the reactant molecules The energy required to bind a substrate to an active site QUESTION 2 Which statement best describes how a catalyst can speed up a chemical reaction? Group of answer … WebAug 13, 2024 · Energy is required to break bonds. Energy is released when chemical bonds are formed because atoms become more stable. Chemical processes are labeled as exothermic or endothermic based on whether they give off or absorb energy, respectively.
