### Collision Theory

For the final, how in depth do we need to know collision theory?

### Re: Collision Theory

I would say that the most important thing we would need to know is that the collisions of a reaction must occur with the reactant molecules being at the correct orientation. Knowing this leads to connecting collision theory to the Arrhenius equation, with A being the collision frequency, which is how often/the likelihood of molecules colliding at the correct orientation. Also, if you increase A, this would lead to correct orientation collisions occurring more frequently, leading to the rate constant, k, to increase. If you increase temperature, more collisions will occur, leading to more correct orientation collisions to occur, also leading to the rate constant, k, to increase.

### Re: Collision Theory

collisions are more likely when the reactants meet at the right orientation and with enough energy. increasing the temperature helps satisfy the need for more molecules of reactant colliding with enough energy

I would think the most important concept from collision theory is that when two molecules collide with not enough kinetic energy they bounce apart. If they are met with more than enough kinetic energy, reactant bonds can break and new bonds can form.

I believe that simply knowing that for a reaction to happen molecules must collide in the proper orientation and with enough kinetic energy to overcome the activation energy to synthesize products

### Re: Collision Theory

Will we need to do calculations for collision theory? Is the equation is not on the constants and equations sheet?
