As a result, immediately after the reaction, the balloon will:- a)Inflate
- b)Deflate
- c)Remain unaltered.
- d)Will change its shape without changing its volume
Correct answer is option 'B'. Can you explain this answer?

The shape of the balloon in maintained by the constant motion of gas molecules filled inside it. As the gas molecules start sticking to the surface, it's motion decreases and the balloon gets deflated.
