What is the relationship between the equilibrium constants for reactions 1,
2, and 3?
Reaction 1: H₂CO3(aq) + H₂O(1) ⇒ HCO3¯(aq) + H3O+(aq)
K₁
K₂
Reaction 2: HCO3¯(aq) + H₂O(1) ⇒ CO3²−(aq) + H3O+(1)
Reaction 3: CO32-(aq) + H₂CO3(aq) → 2HCO3(aq)
K3
K3 = K₁ + K₂
O K3 = K2/K1
OK₁=K₁/K₂
O K3 = K₁K₂
Here are the equilibrium constants for two reactions of nitrogen with
oxygen. What is the equilibrium constant for N₂O (g) + 1/2O₂(g) → 2NO
(g)? Express your answer completely. Do not use scientific notation in
writing your answer. For example, write 1000 instead of 1 x 10³. Express
your answer in two significant figures.
N₂(g) + O₂(g) = 2NO(g)
N₂(g) + 1/2O₂(g) = N₂O(g)
K= 4.1 × 10-31
K=2.4 × 10-18

Follow-up Question

Here are the equilibrium constants for two reactions of nitrogen with oxygen. What is the equilibrium constant for N₂O (g) + 1/2O₂(g) → 2NO (g)?

N₂(g) + O₂(g) = 2NO(g)                        K= 4.1 × 10^-31

N₂(g) + 1/2O₂(g) = N₂O(g)                    K=2.4 × 10^-18
