4. Samples of the gases H2 and SO2 have equal masses and are at the same temperature and volume. Calculate the ratio of rates of impact with the walls (H2: SO2). (A)1 (B)6 (C)32 (D)90 (E)180

1. Equimolar amounts of the gases N2 and H2 are mixed in a closed container fitted with a piston (allowing the volume of the container to change, thus keeping the pressure constant). Calculate the ratio of the final volume of the container to the initial volume of the container when the reaction N2 + 3H2 → 2NH3 goes to completion. (A)2/3 (B)3/2 (C)1 (D)1/3 (E)none of these
