Chemical Reactions
Chemical reactions are processes that involve the rearrangement of atoms and molecules to form new substances. They play a crucial role in numerous natural phenomena and industrial applications.
There are several types of chemical reactions, including:
- Combination reactions: Two or more substances combine to form a single product.
- Decomposition reactions: A single substance breaks down into two or more simpler substances.
- Single-replacement reactions: One element replaces another in a compound.
- Double-replacement reactions: Two compounds exchange ions to form two new compounds.
Factors that affect the rate of chemical reactions include:
- Concentration of reactants: Higher concentrations lead to faster reactions.
- Temperature: Higher temperatures generally increase reaction rates.
- Surface area of reactants: Increased surface area allows for more reactant molecules to interact.
- Presence of a catalyst: Catalysts speed up reactions without being consumed.
