WebIn addition, some groups will increase the rate of reaction ( activating) while others will decrease the rate ( deactivating ). While the patterns of regioselectivity can be explained with resonance structures, the influence on kinetics can be explained by both resonance structures and the inductive effect . Reaction rate [ edit] Web•The rate of an enzyme catalyzed reaction increase with temperature up to maximum called optimum temperature 1-At suboptimal temperature, increasing temperature increase the kinetics energy of the reactant. As they move faster, they move likely to collide and interact with each other and the enzyme. 2-The rate continues to rise until reaches a chinese helmet shang dynasty https://pacificasc.org
