1.	The students of class 9 of City International school were attending an audio-visual session on the collinsion theory of chemical kinetics. When they were viewing the slides given below, their instructor asked them to guess which of the following could be the effective collision and justify their answer.
Answer» Solution : The collisions REPRESENTED by FIGURE (a) are effective collisions. Thecollisions with threshold energy result in a reaction. APART from this, the reactants which collide should have a proper orientation. In figure (b), the nitrogen atom of NO is not near enough to make a bond with any of the near enough to make a bond with any of the oxygen atoms of ozone. In figure (a), the NO molecule collides with `O_(3)` where the direction in which both the reactants collide is PERFECT enough to result in a CHEMICAL reaction.
