Collision Theory
Based on collision theory, the rate of reaction is dependent on the... - answer-frequency of collisions and the fraction of those collisions that are successful Frequency and fraction of sucessful collisions are - answer-dependent on the temperature What is the transition state/activated complex? - answer-The state in which new bonds are forming and old ones are breaking, really close but haven't actually bonded In a reaction, two chemicals reacting must come sufficiently close to one another in the proper orientation in order to break old bonds and form new ones The energy of the transition state is - answer-always higher in energy than products and reactants Difference in energy between reactants and transition state is called - answer-Activation energy What kind of energy is directly related to the rate of reaction? - answer-Activation energy Problems with collision theory - answer-1. According to CT reactions with large amounts of reactants should be really slow and take a long time but lab results say that they do occur and can be fast 2. Sometimes reactions with low numbers of bonds seem to occur fast but in reality they occur very slowly How can you solve problem 1? - answer-Propose a series of elementary steps that make up a reaction mechanism
