What ar five factors that affect the rate of a chemical reaction?

Answer 1

The rate of a Chemical reaction is affected by a number of factors, here are the commonly taught "Five factors of reaction rates":

1-Nature of the Reactants (Based on the atomic structure, ie. the stability of the reactants vs. the stability of the proposed products)

2-Ability of the Reactants to meet ( the state of the reactants: gases and liquids are more likely to react, AND the Surface area: powders have a greater surface area and therefore react quickly)

3- Concentration of the Reactants (the higher the concentration, the more likely the reactants are able to meet and react, thus increasing the reaction rate)

4- Temperature (the higher the temperature of the system, the faster the particles are moving (Kinetic Molecular Theory) and the faster they will collide, thus increasing the reaction rate)

5- Presence of Catalysts (Catalysts increase the reaction rate by overcoming the activation energy. They work by decreasing the reaction barrier of the Rate determining step, which is the slowest step of a chemical reaction)

Of course, there are other factors which affect the reaction rate of a given system, but these are the 5 commonly cited ones they teach you in high school. If you're interested, I'd suggest reading about Collision Theory and Transition State Theory.
