$K X_{2} CO X_{3}$ cannot be manufactured by the Solvay process because

A $K X_{2} CO X_{3}$ decomposes at room temperature
B $KHCO X_{3}$ is a gas
C $KHCO X_{3}$ is too soluble to be precipitated
D $KCl$ is insoluble in water

Answer: C

The process depends on the precipitation of the bicarbonate from the solution.

KHCO X_{3}

is much more soluble than

NaHCO X_{3}

and does not separate, so the route fails for potassium.
