Rate laws

[Amal Aboumerhi 3E]

Hi, could someone provide a summary of the rate laws and when to use them?

[Anahi Guzman 3L]

Hi so we use rate laws to describe the relationship between the rate of a chemical reaction and the concentrations of its reactants. For example we can use rate laws to tell the concentrations of reactions in a table/graph. It also allows us to predict how changes in reactant concentrations will affect the rate of the reaction.

Hi,

Dr. Lavelle has a good doc that talks about different rate laws: https://lavelle.chem.ucla.edu/wp-conten ... amples.pdf

We can also determine the order of the reaction based on which graph gives us a linear graph. By plugging in different experimental values, we can determine which will be linear, therefore determining the order.

Rate laws relate the rate of a reaction to the concentrations of the reactants that must collide in order for that reaction to take place. For example, a second order reaction would have 2 reactants colliding, so it could look like either of the following:
rate = k[A]^2
rate = k[A][B]
For a zero order reaction, the rate is NOT dependent on the concentration of the specified reactant.
