According to the collision theory, for a reaction to be successful, it must have correct orientation of the atoms of the reactants. which of the following must also be true for a successful reaction to occur? (2 points) the particles must have adequate velocity. reactants must have high molecular mass. the collision must have sufficient energy. a catalyst must be present.

The collision must have sufficient energy.

This would be the best choice. For the reaction to be successful, to build a bond for example, the energy necessary to do that must be present.

i just learnt this recently but i need to look through my notes again

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
