rate of reaction quiz

zero order rate laws

r = k (concentration does not affect rate)

if something is only on one side of the reaction can it be a catalyst

no

explain this

first order rate laws

r = k [A]

second order rate laws

r = k[A]²

0 order, 1 order, and 2 order integrated concentration-time relationship

these are on the equations sheet!

0 order linear slope

1 order slope

2nd order slope

kinetics graph

the heat of reaction is also the change in enthalpy and can show you if you have an endo or exothermic reaction

what affects the rate of reaction

how much contact they have

temperature (higher temp means more speed and less stability which is a good thing for the reaction to go)

catalyst (increase rates of reaction and lowers activation energy

concentration of reactants

collision theory graph

to get activation energy on a graph…

R is the universal gas constant 8.314 J/mol K

rules for reaction mechanisms

rate law with multiple products

units for k

remember that the order matters!!

elementary reaction

a process that occurs in a single event, an overall chemical reaction usually has more than one elementary reaction

an unstable, high-energy transition state molecule temporarily formed after the reactant state but before the product state
