Chapter 18 - ROR Flashcards
1
Q
Zero order
A
when the conc of a reaction has no effect on the rate
2
Q
First order
A
when the rate depends on its conc raised to the power of one
3
Q
Second order
A
when the rate depends on its conc raised to the power of 2
4
Q
rate = k [A]ⁿ
A
rate constant = k
rate = initial rate
[A] the conc of reactant
5
Q
CONC TIME GRAPH
A
straight line = 0 order like ╲
curve = 1st order (half life has to be constant) ╰
steeper curve = 2nd order but dont assume ╰
6
Q
RATE CONC GRAPH
A
➜ straight line like ⎯ = 0 order R=K
➜ straight line like ╱ = 1st order = directly proportional
➜ curved ◞ = second order but to make it straight do rate over [conc]²
7
Q
Rate determining step
A
➜ slowest step of the reaction
➜ determines the ROR
