WebbThe differential equations describing the statistical fluctuations of a simple autocatalytic reaction mechanism are set up and solved completely. The fluctuations are found to approach a constant limiting value when the amount of reaction product is large compared to the amount which initiates the reaction. The relative fluctuations which arise from the … WebbA class of autocatalytic reaction networks based on template-dependent replication and specific catalysis is considered. Trimolecular "elementary steps" of simple replicator dynamics are resolved into two consecutive irreversible reactions.
WebbThe most important organic chemistry concepts. In organic compounds, C-C single bond is always a sigma bond. In the C=C double bond, the first bond is always a sigma bond, while the second is a pi bond. If a carbon atom is bonded to 2 other C-atoms, it must then have 2 H-atoms to complete its valency of 4 and attain a stable octet electronic ...
