Chapter 14

Question 1

Average Reaction Rate equation

Answer 1

Avg. Rate= (change in concentration) / (change in time)

Question 2

Rate Constant (k)

Answer 2

k= rate/ concentration

Question 3

Stoichiometry Reaction Rate
(Measuring Progress)

Answer 3

Rate= (1/a)(🔼A/🔼t) = (1/b)(🔼B/🔼t) = (1/c)(🔼C/🔼t)= (1/d)(🔼D/🔼t)

Question 4

Isolation Method

Answer 4

Rate= k(A)^x(B)^y(C)^z
x= r1/r2
Y=r3/r2
Z=r4/r2

Question 5

A product
A) define rate law
B) define linear rate equation

Answer 5

A) rate= (k)(A°)
B) A= -kt + A0

Question 6

First Order
A) solve for rate law
B) solve for k
C) Linear equation

Answer 6

A) rate= - (🔼A/🔼t) = kA
B) k= (M/s) / (M)
C) ln (At/A0) = -kt

Question 7

Second Order
A) solve for rate law
B) solve for k
C) Linear equation

Answer 7

A) rate= k(A)^2
B) k= (M/s) / M^2
C) 1/A= kt+ (1/A0)

Question 8

Half Life Equation

Answer 8

T1/2= (ln)(2/k)

Question 9

Arrhenius Equation

Answer 9

(ln)(k) = (-Ea/RT)+(ln)(A)
A=frequency factor
Ea= activation energy
R= gas constant
T= temperature

Question 10

The 3 Reaction Mechanisms

Answer 10

1) UNIMOLECULAR
2) Bimolecular
3) Termolecular

Question 11

3 types of Catalysis

Answer 11

HETEROGENOUS
•dif phase than reacting medium
HOMOGENOUS
•same phase as reacting medium
ENZYMES
•control rate of bio reactions
