Question

Under which conditions do you expect helium gas to deviate most from ideal behavior?

Answer 1

The normal conditions of helium is 300 k and 1 atm. The conditions that deviate from the ideal behavior do not follow the ideal gas law equation PV = nRT. Among these conditions, the one that did not abide to the ideal gas equation is b. 300 K and 2 atm with the deviation on the pressure.

Answer 2

"300 K and 2 atm" is the condition among the conditions given in the question that you can expect helium gas to deviate most from ideal behavior. The correct option among all the options that are given in the question is the second option or option "b". I hope the answer has helped you.
