Question

Given the following reaction:
XBO3(s) <--> XO(s) + BO2(g)
If the concentration of BO2 at equilibrium was 2.0 M, what is the equilibrium constant (K)?
Select one:
a. Not enough information is given
b. 1.0 M
c. 2.0 M
d. 0.50 M

Answer 1

Solids don't enter into the equilibrium constant expression; therefore, ignoring those the expression is
Keq = (BO2)
Since the (BO2) at equilibrium is given as 2.0 M in the problem, then K must be .....?
