Statement - I: For reaction:

2A(g) + 3B(g) \rightarrow 4C(g) + D(g),

the vapour density remain
constant throughout the progress of reaction.

Statement - II: In all the gaseous chemical reactions, the vapour density remains constant.

View answer and explanation

Correct option: C

If Statement-I is true but Statement-II is false

Option C is correct because Statement-I is true (moles remain constant, so vapor density remains constant), but Statement-II is false (vapor density doesn't always remain constant in gaseous reactions).
