"Rabbi Yitzhak said: At the time God created the world and desired to reveal the depth of His being > from out of the hidden, the light came from the darkness and they were joined together. Because of this, out of darkness came the light and out of the hidden came the revealed and out of the good came evil and out of mercy came severe judgement, and everything is intertwined with everything else...the good inclination and the evil inclination, the right and the left." - The Zohar

Subject: CCL:Reaction rates, very basicHi,are there all the reaction rates derived experimentally? Aren't there any rules/principles that can beobtained from theory? Any "symmetry considerations" giving raise to constraints to the possiblemathematical forms?Thanks in advance,Leonardo
