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. 2 (mol/L)/s
B. 36 (mol/L)/s
C. 24 (mol/L)/s
D. 12 (mol/L)/s
Solution
The rate of a reaction is given by the equation Rate = k[A]^2[B].
Here, the value of k is given as 3, [A] is 2 M and [B] is also 2 M.
Substituting these values into the equation, we get:
Rate = 3 * (2)^2 * 2 = 3 * 4 * 2 = 24 (mol/L)/s
So, the rate of the reaction is 24 (mol/L)/s. Therefore, the correct answer is C.24 (mol/L)/s.
