a) will be valid

b) will not be valid since the ions would experience forces other than due to collision with the walls

c) will not be valid since collisions with walls would not be elastic

d) will not be valid because isotropy is lost

Answer:

The correct options are:

b) will not be valid since the ions would experience forces other than due to collision with the walls

d) will not be valid because isotropy is lost

Explanation:

There will be an electrostatic force acting apart from collision due to the existence of hydrogen ions and a +ve charged wall ABCD.

As a result, the gas kinetic theory will be invalid. Isotropy is lost as a result of the existence of ions in place of hydrogen molecules.
