Studied by 10 peoplereaction rates
the concentration of a substance at different points in time of a reaction
kinetic curve
graph of reaction rate
rate of production
the slope of kinetic curve
concentration effect on reaction rate
if substance is in the rate law, increasing the concentration will increase reaction rate
temperature effect on reaction rate
exponentially related to kelvin temperature
ability to meet as an effect on reaction rates
gas or solutions rapidly react because of the individual molecules. If a solid is grinded, it will react more
catalyst as a reaction rate
catalysts lower activation energy and provide larger rate constat
k
rate constant
order of reaction
found by adding up the exponents of the reactants
Arrhenius equation
k = Ae^(-Ea/RT)
R in Arrhenius Equation
8.314
zero order reaction rate law
Rate = k
First order rate law
Rate = k[A]
integrated first order equation
ln [A]0 - ln [A]t = kt
half life first order equation
t(1/2) = .693/k
second order rate law
Rate = k[A]^2
collision theory
rate of chemical equation is based on collision rate, orientation, and minimum energy
transition state theory
kinetic converts to potential energy, if potential exceeds Ea, reaction occurs and become products
reaction mechanisms
series of steps that occur in a reaction from start to finish
elementary reactions
the smaller reactions that occur in an overall reaction
