LAW OF CONSERVATION OF MASS
Chemical reactions happen all around us. Food spoils, metals rust, candles burn, medicines work inside the body, and fuels produce energy because of chemical reactions. Some reactions happen very fast, while others take a long time.
The rate of reaction refers to how fast or slow a chemical reaction occurs.

Chemical reactions happen when particles collide with enough energy and proper orientation.
Created using Gemini AI
Only effective collisions produce products.
If collisions happen more often and with higher energy, the reaction becomes faster.
The rate of reaction is not fixed. It changes depending on different conditions that affect how particles interact. The following are the factors that affect the rate of chemical reactions. These factors determine how fast or slow a reaction occurs by influencing the frequency and effectiveness of particle collisions.
Temperature measures how hot or cold a substance is. Increasing temperature increases the kinetic energy of particles.
