Consider the following equilibrium reaction:
H2CO3 (aq) = H° (aq) + HCO;" (aq):
K = 5.0 x 10-7
If the initial concentrations of the species are:
[H,CO) = 0.100 M [H"] = 2.00 x 10-5 M [HCO,] = 2.00 x 10³ M
Which one of the statements below describes the relationship between Q and K and then the correct direction of chemical change
Select one:
Oa Q-K so the reaction is at equilibrium.
1bQ<K so the reaction moves to the right.
2CQK so the reaction moves to the left.
Od Qek so the reaction moves to the left.
1e Q-K so the seaction moves to the right
