Chapter 5: Chemical Kinetics

Question 1

Rate of a Reaction

Answer 1

rate = Z x f

Z = total number of collisions occuring per second
f = fraction of collisions that are effective

Question 2

Arrhenius equation

Answer 2

k = Ae -E/ R T

k = rate constant of a reaction
A = frequency factor
Ea = activation energy of a reaction
R = ideal gas constant
T = temperature

Question 3

ΔG - (ΔG<0)

Answer 3

exergonic (energy released)

Question 4

ΔG + (ΔG>0)

Answer 4

endergonic (energy absorbed)

Question 5

rate law

Answer 5

rate = k [A]^x [B]^y

Question 6

zero order reaction

Answer 6

rate = k [A]^0 [B]^0 = k
