A.)
Given the reaction
2A + B ⇋ 4 C (all gases)
concentrations at equilibrium are
A = 0.076 M
B = 0.829 M
If K = 3.32, find the concentration of C and report it in M units.
B.)
Cu (s) + 2 Ag+ ⇋ Cu2+ (aq+) + 2 Ag(s) K = 7.88 x 104
PbCl2 (s) ⇋ Pb2+ (aq) + 2 Cl- (aq) K = 2.4 x 10-4
AgI (s) ⇋ Ag+ (aq) + I- (aq) K = 7.59 x 10-17
Using the information above, determine the value of the equilibrium constant for this reaction.
1/2 Cu2+ (aq+) + Ag(s) ⇋ 1/2 Cu (s) + Ag+
C.)
For the reaction:
CO2 (g) + H2 (g) ⇋ CO (g) + H2O (l)
The initial gas mixture is composed of 2.29 mol H2 and 2.91 mol CO2. At equilibrium, 0.73 mol CO gas are found.
How many moles of H2 remain?
