The rate of a chemical reaction is influenced by many different factors, including reactant concentration, surface area, temperature, and catalysts. In general, increasing the concentration of a reactant in solution, increasing the surface area of a solid reactant, and increasing the temperature of the reaction system will all increase the rate of a reaction. A reaction can also be sped up by adding a catalyst to the reaction mixture.
Sections:
00:00 - Introduction to reaction rate factors
00:04 - Effect of concentration on reaction rate
01:51 - Surface area and reaction rate
03:01 - Temperature and its impact on reaction speed
04:03 - Role of a catalyst in speeding up reactions
05:15 - Summary: how catalysts affect collisions and rate
