The equilibrium constant for the reaction a(g)❝b(g) is 10. a reaction mixture initially contains [a] = 1.1 m and [b] = 0.0 m. which statement is true at equilibrium? the equilibrium constant for the reaction is 10. a reaction mixture initially contains = 1.1 and = 0.0 . which statement is true at equilibrium? a. the reaction mixture will contain [a] = 1.0 m and [b] = 0.1 m. b. the reaction mixture will contain equal concentrations of a and b. c. the reaction mixture will contain [a] = 0.1 m and [b] = 1.0 m.

The reaction mixture will contain [A] = 0.1 M and [B] = 1.0 M

Explanation:

The reaction is:

And the equilibium constant can be expressed in terms of [A] and [B]:

If the initial conditions are that [A] = 1.1 M and [B] = 0.0 M, the conditions at equilibrium will be:

Now we rewrite Keq:

Finally we solve for x:

So at equilibrium, the concentrations are:

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
