what is a rate of reaction
a measure of how fast a reaction occurs
what is the rate equation
a mathematical expression that relates the rate of a chemical reaction to the concentration of its reactants
what is a order of reaction
it describes how the rate of a chemical reaction depends on the concentration of its reactants
what is the zero order reaction
the rate of reaction is independant of the concentration of the reactant
what is a first order reaction
the rate of reaction is directly proportional to the concentration of the reactant
what is a second order reaction
the rate of reaction is proportional to the square of the concentration of the reactant
what is the overall order of reaction
the sum of orders with respect to each reactant in the rate equation
what is the initial rates method
a method to determine the order of a reaction with respect to each reactant and calculate the rate constant
what is the shape of the line on a rate concentration graph for zero order reactions
a horizontal straight line
what is the shape of the line on a rate concentration graph for first order reactions
straight line with a positive slope
what is the shape of the line on a rate concentration graph for second order reactions
curve that slopes upward more steeply as the concentration increases
what are the different ways to monitor the progress of a chemical reaction
- measuring the volume of gas given off
- monitoring changes in pH
- observing colour changes
what are clock reactions
a type of chemical reaction where a visible change, such as colour shift, occurs after a specific time.
what is the Arrhenius equation
π =π΄π ^βπΈπ/π π
what is the Arrhenius equation in natural log
lnK = lnA - Ea/RT
what form of arrhenius can relate to y=mx +c
lnk = (-Ea/RT) - lnA
what is the rate determining step
this is the slowest step which controls how fast the rest of the reaction proceeds
how do you identify the rate determining step
step 1- observe the rate law
step 2- examine the mechanism
step 3- confirm molecularity
