Question 1

In the reaction:

2 N2O(g) + N2H4(g) 3 N2(g) + 2 H2O(g),

one starts with 0.10 mol N2O and 0.25 mol N2H4 in a 10.0 L container. If there are 0.06 mol N2O at equilibrium, how many moles of N2 are present?
◦ 0.02
◦ 0.04
◦ 0.06
◦ 0.09
◦ 0.07

Question 2

Kc is 1.67 × 1020 at 25 °C for the formation of iron(III) oxalate complex ion:

Fe3+(aq) + 3C2O42-(aq) [Fe(C2O4)3]3-(aq)

If 0.0200 mol L-1 Fe3+ is initially mixed with 1.00 mol L-1 oxalate ion, what is the concentration of Fe3+ ion at equilibrium?
◦ 1.44 × 10-22 mol L-1
◦ 0.0100 mol L-1
◦ 8.35 × 1019 mol L-1
◦ 6.94 × 1021 mol L-1
