1) Does 'equilibrium' mean the amounts of reactants and products are equal? Explain.

2) What characteristics define a system at equilibrium? Explain.

3) Consider the equilibrium reaction: 2N2(g) + 3H2(g) ↔ 2NH3(g)
a) Write the equilibrium constant expression, Keq?
b) Calculate the Keq given the equilibrium concentrations: [NH3] = 0.933 M, [N2] = 0.533 M, [H2] = 1.600 M
c) How would the equilibrium change if the pressure of the system is increased? (Shift to products, shift to reactants or no change)
