    Question

    Under identical conditions of temperature and pressure the ratio of the rates of effision of O2 and CO2 gases is given by–

    1. fraction numerator text  ratio of effusion of oxygen  end text over denominator text  ratio of effusion of  end text C O subscript 2 end subscript end fraction equals 0.87    
    2. table row cell stack text  ratio of effusion of oxygen  end text with _ below end cell row cell text end text text r end text text a end text text t end text text i end text text o end text text end text text o end text text f end text text end text text e end text text f end text text f end text text u end text text s end text text i end text text o end text text n end text text end text text o end text text f end text text end text C O subscript 2 end subscript end cell end table=1.17    
    3. table row cell text end text text r end text text a end text text t end text text i end text text o end text text end text text o end text text f end text text end text text e end text text f end text text f end text text u end text text s end text text i end text text o end text text n end text text end text text o end text text f end text text end text text o end text text x end text text y end text text g end text text e end text text n end text text end text end cell row cell text end text text r end text text a end text text t end text text i end text text o end text text end text text o end text text f end text text end text text e end text text f end text text f end text text u end text text s end text text i end text text o end text text n end text text end text text o end text text f end text text end text C O subscript 2 end subscript end cell end table=8.7    
    4. fraction numerator text  ratio of effusion of oxygen  end text over denominator text  ratio of effusion of  end text C O subscript 2 end subscript end fraction=0.117    

    The correct answer is: table row cell stack text  ratio of effusion of oxygen  end text with _ below end cell row cell text end text text r end text text a end text text t end text text i end text text o end text text end text text o end text text f end text text end text text e end text text f end text text f end text text u end text text s end text text i end text text o end text text n end text text end text text o end text text f end text text end text C O subscript 2 end subscript end cell end table=1.17
