CHEMKIN

CHEMKIN is a simulation software used to solve chemical kinetics problems. It is used in microelectronics, chemical, automotive and various other industries. it was originally developed in sandia national laboratories and presently in reaction design. chemkin solves thousands of reaction combinations and helps to understand a particular chemical process though it might involve many sub processes. it is time effecient compared to laboratory processes. this also helps in reducing pollutants that are generated in a real process.
one of the drawbacks of this is it assumes a simple geometry for the dimensions of the reaction vessel which is not the real case. to avoid this KINetics named another software is in conjunction with this.
