How the Rate of the Reaction Is Affected by Activation Energy, Assignment - 1

How the Rate of the Reaction Is Affected by Activation cleverness, Temperature, Frequency of Collisions and Orientation of Collisions - Assignment ExampleIt is evidently clear from the discussion that since Activation Energy (Ea) refers to the amount of energy that must be overcome for a chemical reception to proceed, it varies inversely with the browse of the chemical reaction so, at high Ea, the reaction proceeds slowly whereas, at demoralise Ea, the reaction goes fast. Temperature is typically associated to the kinetic energy (KE) of the system and their direct proportionality to the collisions of molecules per unit time indicates that higher temperature bears corresponding extend in reaction grade while lower temperature favors a decrease in reaction rate. Generally, more(prenominal) frequent collisions yield higher effective collisions per unit time which would increase the rate of chemical reaction whereas less frequent collisions decrease the rate of such reaction. Wit h proper orientation of molecules during collisions, a higher reaction rate is favored while through improper or lack of orientation among colliding molecules, a lower reaction rate can be expected. According to the graph, the minimum energy for a reaction is readily achieved with a greater number of collisions at T2 through the same requirement is met at T1 with fewer collisions. Thus, since the rate of chemical reaction is determined by the number of collisions that temperature facilitates, reaction rate depends on control upon temperature. A certain reaction has an activation energy of 54.0 kJ/mol. As the temperature is increased from 22C to a higher temperature the rate constant increases by a factor of seven. Calculate the higher temperature. Catalyst -- a internality that speeds up a chemical reaction or increases the rate of such reaction by bureau of lowering the activation energy, yet is neither consumed nor is produced in the reaction process.
