- A chemical reaction is a process in which one or more substances (reactants) are converted into one or more different substances (products).
- Chemical reactions involve the breaking and forming of chemical bonds between atoms.
- The reactants are the substances that are present at the beginning of the reaction, while the products are the substances that are formed as a result of the reaction.
- Chemical reactions can be classified into different types, such as synthesis, decomposition, single replacement, double replacement, and combustion reactions.
- The rate of a chemical reaction is influenced by factors such as temperature, concentration of reactants, surface area, and presence of a catalyst.
- Chemical reactions can be represented using chemical equations, which show the reactants on the left side and the products on the right side, with an arrow indicating the direction of the reaction.
- In a balanced chemical equation, the number of atoms of each element is the same on both sides of the equation, ensuring that the law of conservation of mass is obeyed.

Chemical Reactions
Definition: A chemical reaction is a process in which one or more substances, called reactants, are transformed into one or more different substances, called products.
Reactants: The initial substances that undergo the reaction.
Products: The final substances that are formed from the reaction.
Types of Chemical Reactions
- Combination: Two or more substances combine to form a single product.
- Decomposition: A single substance breaks down into two or more products.
- Single-Displacement: One element replaces another element in a compound.
- Double-Displacement: Two elements in two different compounds exchange places.
- Combustion: A substance reacts with oxygen to produce heat and light.
Chemical Equations
- A chemical equation represents a chemical reaction in a symbolic form.
- Reactants are written on the left side of the equation.
- Products are written on the right side of the equation.
- Coefficients are used to balance the equation, ensuring that the number of atoms of each element is the same on both sides.
Factors Affecting Chemical Reactions
- Concentration: Higher concentrations of reactants lead to faster reactions.
- Temperature: Higher temperatures increase the kinetic energy of reactants, leading to faster reactions.
- Surface Area: Increasing the surface area of reactants allows for more collisions and faster reactions.
- Catalysts: Substances that speed up chemical reactions without being consumed in the process.
Thermodynamics of Chemical Reactions
- Exothermic Reactions: Release heat energy to the surroundings.
- Endothermic Reactions: Absorb heat energy from the surroundings.
- Activation Energy: The minimum amount of energy required for a chemical reaction to occur.
Kinetics of Chemical Reactions
- Reaction Rate: The rate at which a reaction proceeds.
- Reaction Order: The power to which the concentration of each reactant is raised in the rate law equation.
- Rate-Determining Step: The slowest step in a multi-step reaction that limits the overall rate.
Applications of Chemical Reactions
- Synthesis of new materials
- Food production and preservation
- Energy production
- Environmental remediation
- Medical treatments
