___ 1.From the choices below, circle which would be a valid rate law expression for a sixth order reaction? (More than one answer is possible)

A)rate = k 3[A]^3[B]

B) rate = k [A][B]^2 [C] [D ]

C)rate = k [A]^3 [B]^3

D)rate = k [A] + [B]^2 +[C]

D)rate = k [A]^2 [B]^4

E)K = [A]^3[B]^4 [C]-1

G)rate = k [A]^3[B]^2[C]^0

Answer 1

aA + bB + cC ---> products

Let the reaction is of order n

Rate = k[A]a [B]b [C]c

n = a+b+c

The valid rate laws for the sixth order reactions are:

C) rate = k [A]^3 [B]^3                    ;n = 3+3 = 6

D)rate = k [A]^2 [B]^4                   ; n = 2+4= 6

E)K = [A]^3[B]^4 [C]-1                    ; n = 3+4-1 = 6
