(A) Indicate following statements as True (T) or False (F):
(a) Higher the molar mass of a gas, faster its diffusion is.
(b) Graham's law states that the rate of diffusion or effusion of a gas is inversely
proportional to the square root of its molar mass.
(c) When NH3(g) and HCI(g) react to form NH,Cl(s), a blue precipitate is observed.
(d) Diffusion is the process whereby gaseous atoms and molecules are transferred from
regions of relatively low concentration to regions of relatively high concentration.
(e) The diffusion rate of a gas depends on the increase or decrease in concentration from
one point to another (concentration gradient), the amount of surface area available for
diffusion, and the distance the gas particles must travel.
(B) If CH4(g) and C4HS(g) are released simultaneously at the left and right ends of a glass tube
with 50 cm length, respectively, at what distance from the left end of the tube will they meet?
(CH4: 16 g/mol, C4H8: 56 g/mol)
