Question | Answer |
rate | change in concentration/change in time rate=k[A]^n |
rate law | relatrate of reaction and concentration of reactants |
rate constant | a constant of proportionality in the rate law *constant of proportionality in the rate law |
intergated rate law | concentration and time |
integrated rate law 0 | [A]t=-kt+[A]0 |
integrated rate law 1 | ln[A]t=-kt+ln[A]0 |
integrated rate law 2 | 1/[A]t=kt+1/[A]0 |
half-life 0 | 1/k*[A]0/2 |
half-life 1 | 0.693/k |
half-life 2 | 1/k*1/[A]0 |
[A]t vs. time slope=-k | zero order straght line |
ln[A]t vs. time slope=-k | first order straight line |
1/[A]t vs. time slope=k | second order straight line |
Arrhenius Equation | k=Ae^-Ea/RT 8.314J/mol*K |
Increase rate of reaction=? | temperature number of collisions(orientation&energy) |
Arrhenius plot y=mx+b | lnk=-Ea/R*(1/T)+lnA lnk2/k1=Ea/R*(1/T1-1/T2) |
rate law based on mechanism | powers of rate law based on coefficients -only for elementary steps on mechanism |
expressing reaction rate | use ooefficient change in concentration change intime |
determining the order and rate constant | M/s, 1/s, 1/Ms |
reaction mechanism problems | sum to over reaction. match? write rate law based on slow step rate forward(k1)=rate backward(k-1) then substitute |
