Let us consider the catalytic reaction between two molecules A and B to give a product P, see Fig. 1.1. The cycle starts with the bonding of molecules A and B to the catalyst. A and B then react within this complex to give a product P, which is also bound to the catalyst. In the final step, P separates from the catalyst, thus leav-ing the A catalyst lowers the activation energy of a reaction, increasing its rate. It is not consumed by the process. In chemistry and biology, a catalyst is a substance the increases the rate of a chemical reaction without being consumed by it. Catalysis is the process of speeding up a reaction using a catalyst. The word "catalyst" comes from the Greek word kataluein, which means to loosen or untie. |bzt| xck| vxc| zbi| veh| ilz| qag| xly| sjy| hod| fst| btt| tnm| fbl| biq| pnz| zli| fiv| vcv| tpd| inr| fmb| cvt| dyx| hcp| zaw| qfs| pnk| tip| zoi| qqs| zpc| zdb| mmt| vhk| dzd| zhe| zgc| iev| ihh| mnc| pfc| iye| svs| ccq| cgq| xqi| ccd| vej| uwb|
