Question

question 1 what must take place in order for a reaction to take place? there has to be the correct amount of energy. the collision must have the correct orientation and the correct amount of energy. the collision must be at the correct orientation. none of these options.

Explanation:

According to the collision - theory in chemistry, for a chemical reaction to occur, reactant molecules must collide with the correct orientation and have the minimum amount of energy (activation energy). Just having the correct orientation or the correct amount of energy alone is not sufficient.

Answer:

The collision must have the correct orientation and the correct amount of energy.
