Answer:
C. The reaction rate at known reaction concentrations
Explanation:
The rate of a reaction is the measure of the speed of a chemical reaction. To find the rate constant of a reaction, the concentration of the reactants must be known.
- Reaction rate is directly proportional to the concentration of the reactants.
- The quantitative relationship between the rate of a reaction and the concentrations of reactants is expressed as the rate law.
- From this we can deduce the rate constant.
