A mixture of a mol of C_(3) H_(8) and b mol of C_(2) H_(4) was kept is a container of V L exerts a pressure of 4.93 atm at temperature T . Mixture was burnt in presence of O_(2) to convert C_(3) H_(8) and C_(2) H_(4) into CO_(2) in the container at the same temperature. The pressure of gases after the reaction and attaining the thermal equilirium with atomsphere at temperature T was found to be 11.08 atm. The mole fraction of C_(2)H_(4) in the mixture is
