Consider the following equilibrium reaction: H2CO3 (aq) ⇌ H+ (aq) + HCO3– (aq); K = 5.0 x 10–7 If the initial concentrations of the species are: [H2CO3] = 0.100 M; [H+] = 2.00 x 10–5 M; [HCO3–] = 2.00 x 10–3 M Which one of the statements below describes the relationship between Q and K and then the correct direction of chemical change? Select one: a. Q = K, so the reaction is at equilibrium. b. Q > K, so the reaction moves to the right. c. Q < K, so the reaction moves to the right. d. Q < K, so the reaction moves to the left. e. Q > K, so the reaction moves to the left.

Question
Consider the following equilibrium reaction:
H2CO3 (aq) ⇌ H+ (aq) + HCO3– (aq); K = 5.0 x 10–7
If the initial concentrations of the species are:
[H2CO3] = 0.100 M; [H+] = 2.00 x 10–5 M; [HCO3–] = 2.00 x 10–3 M
Which one of the statements below describes the relationship between Q and K and then the correct direction of chemical change?
Select one:
a. Q = K, so the reaction is at equilibrium.
b. Q > K, so the reaction moves to the right.
c. Q < K, so the reaction moves to the right.
d. Q < K, so the reaction moves to the left.
e. Q > K, so the reaction moves to the left.
