the collision theory
A.-
1.-It is pretty obvious that if you have a situation involving 2reactants they can only react together if they come into contact with each other. They first have tocollide, and then they may react. Why “may react”?
Because it do not only depend of the contact, of the collision, besides that, the reactants must have a certain minimum of energy, that is call theactivation energy, that needs certain amount to get the “strong” to react, if doesn’t have that certain amount it won’t react.
2.-What is the Activation energy?
Is the certain amount of energy needed toreact, to broke the bonds and make may be another substance, it is need a certain amount to react, and when the reaction is finished is released an amount of energy.
B.
1.-Does a reaction take placeif the energy of the collision is less than the activation energy?
No it doesn’t because it doesn’t have that certain amount require
2.-Does a reaction take place if the energy of the collision isgreater than or equal to the activation energy?
Yes it does, because this reactants attach in the certain place and with the energy require or more.
3.-Does a reaction take place if there issufficient energy, but incorrect orientation?
No it doesn’t, it can’t be, because one of the conditions is that apart from having the energy required it has to fit or rather to collision in the right place.C.
1.-Did a reaction take place between Reactant A and Reactant B in Scenario 1? Why or Why not? Explain your reasoning in terms of the nature of the collision.
No , because the batter didn’t eventouch the reactant B (the baseball), and it is impossible to occur a reaction if the reactants didn’t touch, they didn’t make any collision.
2.-Did a reaction take place between Reactant A andReactant B in Scenario 2? Why or Why not? Explain your reasoning in terms of the nature of the collision.
No, because the reactant B didn’t have the energy for even arrive to the reactant A, besides, that...
