Spontaneous reactions __ are always exothermic always take place at a rapid rate always release free energy always result in increased disorder of the system
Why does a higher temperature cause a reaction to go faster? Collisions occur with greater energy only. There are more collisions per second only. There are more collisions per second and the collisions are of greater energy. There are more collisions per second or the collisions are of greater energy.
