Eqn. becomes PV=nRT. <br/> (c ) is correct because van der Waals coefficients depend only on the <a href="https://interviewquestions.tuteehub.com/tag/nature-1112013" style="font-weight:bold;" target="_blank" title="Click to know more about NATURE">NATURE</a> of the gas. <br/> (d) is correct because due to inward pull on the <a href="https://interviewquestions.tuteehub.com/tag/molecules-563030" style="font-weight:bold;" target="_blank" title="Click to know more about MOLECULES">MOLECULES</a> striking the <a href="https://interviewquestions.tuteehub.com/tag/wall-1448655" style="font-weight:bold;" target="_blank" title="Click to know more about WALL">WALL</a>, the pressure is lower.</body></html>
