A chemical reaction is said to be in a state of equilibrium when: (a) the rate of forward and reverse reactions are equal (b) the concentrations of reactants and products remain constant over time (c) no reactant is broken down and no product is formed again (d) a & b are correct 22. An equilibrium reaction is said to be in a state of dynamic equilibrium and not in a state of static equilibrium. This statement is: (a) true (b) false (c) cannot tell (d) only an experiment can tell 4.

8. There are three steps in the formation of a solution. It is necessary to overcome the intermolecular forces present within the solute. It is also necessary to overcome the intermolecular forces present within the solvent. Both of these steps require energy related to the strength of the intermolecular forces. The final step in the formation of a solution involves the creation of new intermolecular forces between the solute and solvent. This energy release is related to the strength of the intermolecular forces created. Which of the following illustrates a situation most likely to release the greatest amount of energy? (A) NaCl(s) + H₂O(l) (B) CH,OH(1) + H₂O(1) (C) CCL (1) + Cl₂(g) D) CCL(1)+CH,OH(1) -
