but many will not. Orientation effects slow the reaction, but not by much. Some reactions involve very large molecules with very specific reaction sites, and in these a low fraction of collisions occurring lead to products. Conclusion: The more specific a reaction site, the slower the reaction. II. Chemical change: In this change, chemical reaction takes place and completely a new substance with different properties is formed. There are changes in chemical properties and composition of substance. ex: 2Mg(s) + O 2 (g) → 2MgO(s) Here, the chemical composition and properties of product MgO is totally different from its reactants Mg and O.
