The rate law uses the molar concentrations of reactants to determine the reaction rate. Hence, option (C) is the correct option
A rate law shows how the rate of a chemical reaction depends on reactant concentration.
For a reaction such as aA → products, the rate law generally has the form
rate = k[A]ⁿ,
where,
Typically, increased concentrations of reactants increases the speed of the reaction, because there are more molecules colliding and reacting with each other.
Hence , The rate law uses the molar concentrations of reactants to determine the reaction rate. Hence, option (C) is the correct option
