Question

describe the kinetics of first order reaction.why is a first order reaction never completed?........plz anyone help me to solve questions​

Answer 1

Answer:

Basically in a first order reaction the rate of the reaction is directly proportional to the concentration of the reactant left . so as the reaction proceeds the concentration of the reactant goes on decreasing and rate becomes more slow as time passes hence it never comes to end.

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

First order kinetics occur when a constant proportion of the drug is eliminated per unit time. Rate of elimination is proportional to the amount of drug in the body. The higher the concentration, the greater the amount of drug eliminated per unit time.
