According to le chatelier’s principle, which statement is true?
a. the equilibrium constant is unchanged by temperature changes.
b. the equilibrium constant changes with a change in temperature.
c. the equilibrium constant increases with the concentration of reactants.
d. the equilibrium constant decreases with the concentration of products.

B. The equilibrium constant changes with a change in temperature.

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The equilibrium constant in terms of concentration is written as :

Thus equilibrium constant will not change with increase in concentration of products as concentration of reactants will be increased proportionally and ratio remains same.

Equilibrium constant will not change with increase in concentration of reactants as concentration of products will be increased proportionally and ratio remains same.

Equilibrium constant changes with a change in temperature.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the answer is minerals.
