Reactants that arewill appear in the rate law as the concentration of the reactant squared. a. zero order.
b. first order.
c. second order.
d. fourth order.

The correct answer is c. second order

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

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
