Question

What is the rate of a reaction if the value of k is 3 and [A] and [B] are each 2

M?
Rate = k[A]2[B]
A. 12 (mol/L)/S
B. 2 (mol/L)/S
C. 36 (mol/L)/s
D. 24 (mol/L)/s

Answer 1

rate = 24 (mol/L)⁻³/s

Step-by-step explanation:

Rate equation:

Rate = K[A]²[B]

Concentration of A = 2M

Concentration of B = 2M

K = 3

by substituting values,

rate = 3 (mol/L)⁻³/s×[2]² ×[2]

rate = 24 (mol/L)⁻³/s
