Chemistry - Ideal Gas Question with Solution | TestHub

Equal moles at the same V and T give equal partial pressures, so (a) is false. Both gases have the same average kinetic energy per molecule; the lighter H₂ has the greater average speed (b) and hits the walls more often (c). Momentum transfer per collision scales as m·v ~ sqrt(mT), so the heavier O₂ molecule applies more average force per collision (d). Hence (b), (c), (d).
