Question

By the addition of inert gas to the system 2HI gives H2 + I2 the degree of dissociation of HI will be
Ans not altered I need explanation...

Answer 1

Answer:

There is no effect when an inert gas is added at a constant volume.

But at constant pressure it tends to proceed in the direction where there is more number of moles.

Since the number of mole is same on both sides of the reaction , it is not altered.

Explanation:

At const pressure :

on addition of inert gas volume increases

molarity = const

molarity= no of moles/volume

thus if volume increases no of moles also has to increase for molarity to be constant

Answer 2

Answer:it wont be altered

Explanation:bcoz there are two conditions for inert gas addition

1.Constant pressure 2.Constant volume

Here ng=2-2=0

So even in const pressure or volume the degree of dissociation wont change
