Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isĂâĆ„ĂâĆ„=ĂââșĂââșĂââșĂââșĂââșĂââșĂââ°Ăââ°more accurate estimates can be made with the van der waals equationĂâĆ„ĂâĆ„=ĂââșĂââșĂââșĂââșĂââșĂââșĂââ°Ăââ°ĂąâĂââșĂââșĂâĆșĂâĆșĂąâĂâĆŸĂâĆŸĂââșĂââș2Ăââ°Ăââ°2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0ù°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?
