Rates of Reaction

what is the zero order [R]⁰?

the rate is unaffected by conc of reactants

what is the first order [R]¹?

the rate is directly proportional to conc of reactants

what is the second order [R]²?

as [reactants] increases the rate is directly proportional conc of [reactants]²

how do you find the rate of k[y][z]²?

you add the indices

what is chemical half life?

time taken for the conc to halve

what is chemical half life applicable for?

1st order reactions only

what is the half life equation?

k= ln2 / t_1/2

how does 0th order affect the conc vs time graph?

no rate effect

how does 1st order affect the conc vs time graph?

proportional rate to conc

how does 2nd order affect the conc vs time graph?

as conc doubles, rate quadruples

what are 2 forms of continuous measuring?

quenching and colorimetry 

what is the initial rate measurement useful for telling us?

how reactants or catalysts affect the order of reaction 

how does the arrhenius equation relate to y=mx+c

y=lnK m= -Ea/R x= 1/T c=lnA
