Factors Affecting Rates of Reaction & Collision Theory (High School Science)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Collision Theory The role of sufficient energy (activation energy) in collisions. The importance of the frequency of collisions. 2. The effect of Temperature on reaction rate. How temperature influences the energy of particles and the frequency of their collisions. 3. The effect of Concentration and Pressure on reaction rate. How the number of particles in a given volume affects collision frequency. 4. The effect of Surface Area on reaction rate. How the surface area to volume ratio impacts the frequency of collisions. 5. The role of Catalysts in chemical reactions. How catalysts provide an alternative reaction pathway with a lower activation energy. Using reaction profile diagrams to illustrate the effect of a catalyst. Examples of catalysts, including transition metals and enzymes. ** CHAPTERS ** 0:26 Collision Theory and Activation Energy 1:42 How Temperature Affects Reaction Rate 2:11 How Concentration and Pressure Affect Reaction Rate 2:39 How Surface Area Affects Reaction Rate 3:19 How Catalysts Affect Reaction Rate ** PLAYLISTS **    • Middle School Science (Life Science, Earth...      • High School Science   #NGSS #Chemistry #study #revision #school #exam
