EXAMPLE 4:
When molecules collide, for a reaction to take place, two conditions must be met.
Firstly, they must have sufficient energy to react and secondly, they must have the
right orientation. This means that the ends of the molecules that are going to react
must be in contact with each other.
Raising the temperature speeds up a chemical reaction.
Which of the following could be responsible for this?
1. More collisions take place
2. The average collisions has more energy
3. The orientation of the molecules is more favourable.
