what is rate constant ? what are characteristics
Answers
What are the characteristics of rate constant?
1) Rate constant is a measure of the rate of the reaction. Larger the value of k, faster is the reaction and vice versa. 2) Different reactions have different values of k. 3) At a fixed temperature, the value of k is constant and is characteristic of the reaction
Answer:
The characteristics of rate constant are as follows
(1) The rate constant depends upon the nature of the reaction.
(2) Higher the value of the rate constant, faster is the reaction.
(3) Lower the value of the rate constant, slower is the reaction.
(4) By increasing the temperature. the magnitude of the rate constant increases.
(5) For the given reaction, the rate constant has higher value in the presence of a catalyst than in the absence of the catalyst.
(6) The reactions having lower activation energy have higher values for rate constants.
