For a reaction that follows the general rate law, Rate = k[A][B]2, what will happen to the rate of reaction if the concentration of A is increased by a factor of 5.00?4

Final answer:

If the concentration of A is increased by a factor of 5.00, the rate of the reaction will quadruple.

Step-by-step explanation:

The rate of the reaction will quadruple if the concentration of A is increased by a factor of 5.00. This is because the reaction follows a second-order rate law, which means the rate is proportional to the square of the concentration of A. When the concentration is increased by a factor of 5.00, the squared concentration is increased by a factor of 25, resulting in a quadrupling of the reaction rate.

Answer:

The rate will increase by a factor of 5.00 too.

Step-by-step explanation:

Hello,

In this case, given the rate law:


r=k[A][B]^2

Thus, we can notice it is first-order respect to A, for that reason, increasing its concentration by a factor of 5.00, increase the rate by a factor of 5.00 as well.

Moreover, if the concentration of B is increased by the same factor, the rate will increase by a factor of 25.00, since the rate is second-order respect to B (it is squared).

Best regards.
