Question 1

5.00 mol of ammonia are introduced into a 5.00 L reactor vessel in which it partially dissociates at high temperatures.
2NH₃(g)

3H₂(g) + N₂(g)
At equilibrium at a particular temperature, 1.00 mole of ammonia remains. Calculate K_c for the reaction.

Question 2

A solution was prepared such that the initial concentrations of Cu²⁺(aq) and CN^–(aq) were 0.0120 M and 0.0400 M, respectively. These ions react according to the following chemical equation

Cu²⁺(aq) + 4CN^–(aq)

Cd(CN)₄^2–(aq)

K_c = 1.0 × 10²⁵

What will be the concentration of CN^–(aq) at equilibrium?
