2 A(g) + B(g) \longrightarrow⟶ 2 C(g)

Rate = k [A][B]

At the beginning of one trial of this reaction, [A] = 3.0 M and [B] = 1.0 M. The observed rate for the formation of C is 0.36 mol L-1 sec-1.



The numerical value of k, the rate constant, is closest to


108
0.040
0.12
6.0

Respuesta :

Answer:

The correct answer is 0.12.

Explanation:

 According the reaction kinetics we all know that

    Rate=k[A][B]

K= rate constant

[A] = Concentration of A

[B] =Concentration of B

     R=0.36mol/litre/sec

    K=?

K= rate÷[A][B]

   = 0.36÷3

    =0.12
