Question

What is the rate of a reaction if the value of kis 3 and [A] and [B] are each 2
M?
Rate = K[A]²[B]
OA. 12 (mol/L)/s
OB. 24 (mol/L)/s
OC. 2 (mol/L)/s
о D. 36 (mol/L)/s

Answer 1

The rate of reaction of the value of KIS 3 and [A] and [B] are each 2M is: 24 (mol/L)/s (Option B)

What is rate of reaction?

In chemistry, the rate of reaction describes how quickly a chemical reaction develops.

It is frequently described in terms of either the concentration of a reactant that is spent in a unit of time or the concentration of a product that is generated in a unit of time (amount per unit volume).

What is the calculation that supports that above answer?

Recall that the rate equation is:
Rate = K[A]²[B]

Hence:

Concentration of A = 2M

Concentration of B = 2M

K = 3

Taking the values and substituting them, we have:

Rate = 3 (mol/L)⁻³/s×[2]² ×[2]

Rate = 24 (mol/L)⁻³/s

What is the usefulness of Rate of Reaction?

The rate of reaction can be used as a valuable diagnostic tool. We may devise strategies to increase production by learning how quickly things are created and what slows down reactions.

This knowledge is necessary for the industrial production of various chemicals, such as:

• fertilizers
• medications, and
• home cleaners.
