Half-life period of a first-order reaction is 1386 seconds. The specific rate constant of the reaction is :
Answers
The units of a reaction rate are concentration / time. This is most often M / s, where M is molarity (moles per liter) and s is time in seconds.
P.S. Don’t get M / s (molarity per second) confused with m / s (meters per second)

matters are made up of atoms. Then ask the next question, "What are atoms?"
Atoms are the smallest part of an element. They are composed of nucleus and electrons, electrons surround nucleus. Elements are identified by the number of electrons in orbit around nucleus of atoms and by the number of protons in nucleus.

Nucleus is made up of protons and neutrons, and the number of protons and neutrons are balanced. Neutrons have no electric charge, protons have positive charges (+) and electrons have negative charges (-). A positive charge of proton equals a negative charge of electron.
Electrons are bound in their orbit by attraction of protons, but electrons in the outer band can become free of their orbit by some external forces. These are referred to as free electrons, which move from one atom to the next, electron flows are produced. These are the basis of electricity. Materials that allow many electrons to move freely are called conductors and materials that allow few free electrons to move are called insulators.
All matters are made up of atoms that have electric charges. Therefore, they have electric charges. For the matter that has a balanced the number of protons and electrons, positive charge force and negative charge force are balanced. It is called neutral state of an atom. (The number of protons and electrons remains equal.)
