6.5 Rate Law

Question 1

Rate law

Answer 1

An equation that connects the rate of the reaction with the concentration of its reactants at a given temperature and pressure.

Question 2

what does k stand for in the equation

Answer 2

k is the rate constant (determined experimentally, and varies with temperature).

Question 3

what do m and n stand for in the equation

Answer 3

Exponents m and n CANNOT be obtained from the balanced equation. CAN only be determined
from experimental data. (m, n >0).

Question 4

order of reaction

Answer 4

Each exponent in the rate law equation (m and n)
is called an ORDER of REACTION. (describes the
relationship between the initial concentration of
the reactant and its rate)

Question 5

total order

Answer 5

TOTAL order is simply the SUM of the individual
orders.

Rate = k[A]1[B]2

1+2 =3

Question 6

Any number raised to the power of zero is….
ONE. This means that the concentration of
that reactant does ___ affect the _____ of
reaction.

Answer 6

not; rate

Question 7

rate constant

Answer 7

determined empirically
and is unique for a single reaction at a
specified temperature

Question 8

initial rate

Answer 8

the rate determined just after
the reaction begins (just after t = 0 s)

Question 9

If the exponent of [A] is 1, then the reaction is _____ order with respect to A.

Answer 9

first

Question 10

If the exponent of [A] is 2, then the reaction is ________ order with respect to A

Answer 10

second
