Question 1
If 0.50 mole H2(g) and 1.0 mole He(g) are compared at standard temperature and pressure, the two gases will:
◦ have equal effusion rates
◦ have equal average molecular velocities
◦ have equal average molecular kinetic energies
◦ occupy equal volumes
◦ have equal weights
Question 2
If 250. L of nitrogen reacts with 582 L of hydrogen by the reaction:
N2(g) + 3 H2(g) → 2 NH3(g),
how much nitrogen is unreacted? All gases are at the same temperature and pressure.
◦ 1.9 × 102 L
◦ 3.3 × 102 L
◦ 56 L
◦ 3.0 × 102 L
◦ 41 L
