ACorrect orientation and equal molar mass
BCorrect orientation and sufficient energy
CSufficient energy and a solid catalyst
DEqual molar mass and sufficient energy
Answer & Solution
Correct answer: B. Correct orientation and sufficient energy
1. Particles must collide before they can react, but a collision alone is not enough.
2. The colliding species must be turned so that the atoms which will bond can actually touch.
3. The collision must also carry enough energy to let the valence shells interpenetrate.
4. Molar mass and the presence of a catalyst are not among these two requirements.
