Question

Describe characteristics of rate constant k

Answer 1

Characteristics of rate constant

1. Greater the value of rate constant, faster is the reaction.

2. Each reaction has a particular value of rate constant at a particular temperature.  

3. The value of rate constant for the same reaction changes  with temperature.

4. The value of rate constant for a reaction doesn’t depend upon the concentration of the reactants.

Answer 2

$\huge\sf\underline\blue{Explanation}$

☆Rate constant is independent of Initial concentrations

☆Rate constant is depends on Temperature and positive catalyst

☆It has different values for different reactions

☆Units of rate constant is depends on order of reaction

☆When there is increase in temperature and increase in positive catylyst rate constant also increases
