initiate the reaction. It represents the minimum energy needed to form an activated complex during collisions between reactant molecules. In slow reactions‚ the fraction of molecules in the system moving fast enough to form an activated complex when a collision occurs is low so that most collisions do not produce a reaction. However‚ in a fast reaction the fraction is high and therefore‚ collisions produce a reaction. In 1889‚ Svante Arrhenius demonstrated that the rate constant k is related to

Road accidents also called traffic collision are caused by humans when they overlook laid down rules and regulations governing the use of roads. According to the population reference Bureau “an estimated 1.2 million people are killed in road crashes each year and as many as 50 million are injured”

MEDIUM ACCESS CONTROL PERFORMANCE IN SATELLITE COMMUNICATION ABSTRACT MAC protocols are designed to coordinate the transmission of packets‚ retransmission of damaged packets‚ and resolution of collisions among stations during a contention period . The MAC protocols include fixed assignment protocol‚ demand assignment protocol‚ random access protocol‚ reservation protocol‚ hybrid of reservation protocol and random access protocols and adaptive protocols.

greater than one another. Collision model provides characteristics of chemical reaction. Molecules must collide in order to react; and Characteristics such as higher concentrations‚ high temperature‚ etc. plays the role of increasing the speed of reaction or having more collisions. Scientists use collision model to understand why some molecules react and some do not. Also see how strong collision can break the bond of molecules to produce the product. molecules collision needs energy to break bonds

According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area increases the rate of reaction increases. Background information: “Collision theory is a theory proposed independently by Max Trautzin 1916 and William Lewis in 1918‚ that qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions. The collision theory states

affect the reaction. The collision theory explains that in order for a reaction to occur‚ reacting particles must collide with one another. An effective collision makes reactants result in a reaction and for to be successful two things must happen‚ the correct orientation of reactants‚ and the sufficient collision energy. The orientation of reactants explains that reacting particles must collide with the proper orientation relative to one another‚ for sufficient collision energy‚ it explains that

The collision theory stipulates that in order for a chemical reaction to transpire‚ the reactant particles must possess sufficient energy and the correct collision geometry. There are five main factors which affect the rate of reaction‚ including temperature‚ concentration‚ particle size‚ pressure and the presence of
