Question

Consider the following representation where A and B are reactants.

[A + B → textproducts]

Which rate law correctly applies to this reaction?
a) (K[A])
b) (K[AB])
c) (K[B])
d) (K[A][B])

Answer 1

The correct rate law for the reaction A + B → products is (K[A][B]). It is a second-order reaction and the rate constant, K, represents the specific rate constant for the reaction.

Step-by-step explanation:

The correct rate law for the reaction A + B → products is (K[A][B]). This is because the rate of the reaction is proportional to the concentrations of both reactants A and B. This type of reaction is classified as a second-order reaction, as it is first order with respect to both reactants. The rate constant, K, represents the specific rate constant for the reaction. Therefore, the correct rate law for this reaction is (K[A][B]).
