L1- Reaction Kinetics Flashcards
1
Q
Zero order reaction
A
A= A0 -kt
2
Q
First order reaction
A
A/A0 = exp(-kt)
3
Q
Second order reaction
A
1/A = 1/A0 +kt
4
Q
First order- Rate equation and units of k
A
r=kA -> dA/dt=-kA
k = 1/time
5
Q
Zero order- Rate equation and units of k
A
-r=-dA/dt=k
k=mass/time
6
Q
Second order- Rate equation and units of k
A
r=-dA/dt=-kA^2
k = 1/(mass x time)
7
Q
Axis of a graphical plot to determine k for zero order reaction
A
A against t
8
Q
Axis of a graphical plot to determine k for first order reaction
A
ln(A/A0) against t
9
Q
Axis of a graphical plot to determine k for second order reaction
A
1/A against t
