Question

What is the rate of a reaction if the value of kis 0.1, [A] is 1 M, and [B] is 2 M?

Rate = K[A]2[B]2
A. 1.6 (mol/L)/s
B. 0.8 (mol/L)/S
C. 0.2 (mol/L)/S
D. 0.4 (mol/L)/S

Answer 1

D. 0.4 (mol/L)/S

Step-by-step explanation:

You simply have to plug in the given values into the rate law.

Rate = k[A][B]

Rate = (0.1)(1)²(2)²

Rate = (0.1)(1)²(4)²

Rate = 0.4
