Question

What are the characteristics of rate constant?

Answer 1

1. The rate of a reaction is measured by its rate constant. The pace of the reaction increases as k increases.
2. A particular reaction has a definite value of k at a particular temperature.
3. The value of the rate constant for a particular reaction increases with an increase in temperature.
4. The rate constant does not depend upon the initial concentration of reactants.
5. Its units depend upon the overall order of reaction (the sum of powers to which the concentration terms have been raised in the rate law). For a reaction of order n, the units of the rate constant are mol¹⁻ⁿ n^−l s⁻¹.
