Question

The reaction A + 2B + C - Products has a rate law of

Rate = k[A]^2|B]. By what
factor would the reaction rate change if [A] is tripled?

Answer 1

Step-by-step explanation:

The rate law for the reaction A + 2B + C - Products is given as:

Rate = k[A]^2[B]

This means that the reaction rate is directly proportional to the square of the concentration of A and the concentration of B raised to the first power.

If the concentration of A is tripled, the new concentration of A will be 3[A].

Substituting this new concentration into the rate law, we get:

New rate = k[(3A)^2][B] = 9k[A]^2[B]

Therefore, the new rate is 9 times the original rate.

So, if [A] is tripled, the reaction rate would increase by a factor of 9.
