Consider the reaction:
2NACI + CaC03 + Na2CO3 + CaCl2
Write the equilibrium expression for this reaction? Be sure to consider states of matter as you enter the
chemicals. Put the substances in the same relative order as in the reaction. Enter the correct formula for
substances. If the substance should not be included in the equilibrium expression, place the formula where
it would belong and enter a 0 as the exponent.
K eq =
Write the equilibrium expression for:
Na2CO3 + CaCl, → 2 NaCl + CaCO3
K eq =
How do the equilibrium constants compare?
O The first K is twice as large as the second K.
O The first K is half the nmber of the second K.
O Experimental evidence is needed to determine this.
O The two K values are recipricals of one another.
O They are unrelated.
