If the concentration of reactants in a chemical reaction is unity, then the rate is called:
- A
Unit rate constant
- B
Specific rate constant
- C
Relative rate constant
- D
Average rate constant
A specific rate constant at a given temperature may be defined as the rate of reaction when the molar concentration of each reactant is unity.
The unit rate constant is the constant that is used to convert quantities from one unit to another. It is not related to chemical kinetics. Hence, this option is incorrect.
The specific rate constant is the rate at which the concentration of all reactants is taken as unity. Hence, this option is the correct one.
A relative rate constant refers to the ratio of the respective rate constants of two reactions. Hence, this option is also incorrect.
Average rate constant is not a term used in chemistry. Hence, this option is also incorrect
