Question

H2CO3(aq) + H2O(l) H3O+(aq) + HCO3-1(aq).
What is the correct equilibrium expression?

Answer 1

@matt101 can you help?

Answer 2

What are the options?

Answer 3

Remember the general form of the equilibrium constant expression is the concentrations of products over the concentrations of reactants. Each thing is raised to an exponent that is the same as its stoichiometric coefficient in the chemical equation.

Based on this, what do you think the answer is to this question?

Answer 4

Ka=[H3O+][HCO1−3][H2CO3]

Answer 5

Ka=[H3O+][H2CO3][HCO1−3]

Answer 6

Ka=[H2CO3][H2O][H3O+][HCO1−3]

Answer 7

Ka=[H3O+][HCO1−3][H2CO3][H2O]

Answer 8

that literally sounds like a second language @matt101

Answer 9

so the equilibrium constant is equal to the product of the concentration of the reactants / product of the concentration of the reactants.
Haveng: [HCO3-1][H3O+]/[H2O][H2CO3]

Answer 10

is that one of the options..?
