Question

Give the schematic representation of proper and improper alignment of reactant for a general reaction A2 + B2 = 2AB

Answer 1

Answer:

sum of total reactant is equal to the total product produce during reaction

2A+2B =2AB

Answer 2

Answer:

The schematic representation of proper and improper alignment of reactant:

AA + BB →AB + AB . (Effective collision)  

AA + BB  →  2AB (AA + BB) no reaction  (Ineffective collision)  

Explanation:

• The reactant molecules must collide with favourable orientation in order to facilitate the breaking of "old bonds" and formation of "new bonds". The orientation ensures "direct contact" between the "atoms of the molecules" involved in collisions to makes it effective .
• The  collisions between the reacting molecules are not effective in producing a chemical change. Only a fraction of total number of collisions are effective and lead to a reaction resulting in the formation of products.
