Expert Solution

A 0.905 mol sample of Ar gas  Volume-22.6 liter container at 31.6 °C.

 

 increase in volume- 45.2 L holding the temperature constant.

Given that the Volume is increased at constant temperature.

As we know at constant temperature the average speed of particle remains same .

So if the speed remains same then the force per molecule-wall collison will also remain same.

Hence , The answer is remains the same.


There will be no effect on Force per molecule-wall collesion .
