Question

Reactants that are_____will appear in the rate law as the concentration of the reactant squared.

a. zero order.
b. first order.
c. second order.
d. fourth order.

Answer 1

The correct answer is c. second order

Step-by-step explanation:

In a rate law, second order means that the chemical rate is related with the reactant concentration raised to 2. For example, if the chemical equation is:

A ⇒ B

A is the reactant and it is a second order reaction, so the rate law will be:

r = [A]²
