Diffusion and Effusion

Consider the following statements and arrange in the order of true/false as given in the codes. The correct order of True/False of the following statements is : S_1 :Rate of diffusion and effusion of a gas increases by increasing the pressure and decreasing the temperature. S_2 :An ideal gas has vander waal's constant a and b equal to zero. S_3 :If an ideal gas is expanded adiabatically against a constant pressure then TV^(gamma-1) =constant

The Graham's law states that ''at constant pressure and temperature the rate of diffusion or effusion of a gas is inversely proportional to the squar root of its density Rate of diffusion prop (1)/(sqrt(d)) If r_(1) and r_(2) represent the rates of diffusion of two gases and d_(1) and d_(2) are their respective densities, then r_(1)/(r_(2))=sqrt((d_(2))/(d_(1))) r_(1)/(r_(2)) =sqrt((M_(2))/(M_(1))) xx P_(1)/(P_(2)) (V_(1)xxt_(2))/(V_(2)xxt_(1)) = sqrt((d_(2))/(d_(1))) = sqrt((M_(2))/(M_(1))) V prop n (where n is no of moles) V_(1) prop n_(1) and V_(2) prop n_(2) If some moles of O_(2) diffuse in 18 sec and same moles of other gas diffuse in 45sec then what is the molecular weight of the unknown gas ? .
