All the Books in the Bible were only estimated to have been written to a certain year, nothing definite. Even who the Authors of the Books was/were are still being debated. So your question regarding when "each Chapter was written" is impossible to answer at this point in time.
Some of them are names after people because of who wrote them or inspired them. But a lot of the books are in fact letters to cities, Corinthians for example was written for the leaders in Corinth, although written by Paul.
All the psalms were written anonymously, and scholars say that the earliest were written during the Babylonian Exile and then during a period of around two hundred years. Thus, we can not be certain exactly which is the oldest surviving psalm to be written, nor of course who wrote it. However tradition holds that the psalms were written much earlier than this, with the earliest of them written by King David.
A rational number is one that can be written as a simple fraction, with integers in the numerator and denominator. A number that can't be written this way is irrational.Also, a rational number, when calculated as a decimal, will either terminate (for example, 1/4 = 0.25), or it will repeat a certain digit or group of digits over and over, after a certain point (for example, 1/6 = 0.16666666...)
