1.	5 mole of an ideal gas expands isothermally and irreversibly from a pressure of 10 atm to 1 atm against a contant external pressure of 1 atm. W_("irr") at 300K is:
Answer» `-15.921kJ` `-11.224kJ` `-110.83kJ` none of these Solution :`W_("irr") = - P_("ext") (DELTA V) = -1 XX ((nRT)/(P_(2)) - (nRT)/(P_(1)))` `= -1 xx (5 xx 0.0821 xx 300) ((1)/(1) - (1)/(10))` `= -110.835` L-atm = 11.22 KJ
