Question
1. If the value of Kc for a given reacti on at a given temperature is a small number, the energy of the products is likely to bethe energy of the reactants because a. greater than; the value of K, favors the reactants b. the same as; the value of Kc favors neither the products nor the reactants c. less than; the value of Kc favors the reactants d. greater than; the value of K, favors the products e. less than; the value of Kc favors the products 2. A solution is prepared by diluting 0.10 mol formic acid (2H) with water to a volume of 1.0 L. At equilibrium, the HjO concentration is 4.2 x 10-3 M. What is the equilibrium constant for the dissociation of formic acid in water? HCO,Hag)+ H200)HCO (aq)+Ho (aq) a. 1.8 x 10-6 b. 2.4 x 101 c. 5.4 x 103 d. 4.2 x 102 e. 1.8 x 104 3. If the value of K, for a given reaction at a given temperature is a large number, the energy of the products is likely to be_the energy of the reactants because a. greater than; the value of Kc favors the products b. greater than; the value of Kc favors the reactants c. less than; the value of Kc favors the reactants d. less than; the value of Ke favors the products e. the same as; the value of Ke favors neither the products nor the reactants 4. The equilibrium constant for a particular chemical reaction is a. dependent on the total pressure of the reaction. b. dependent on the temperature of the reaction. c. a numerical value between-oo and +oo, d. unreliably determined if variable amounts of either solid or liquid reactants or products are present e. both b and c.Explanation / Answer
1 ans:- e option
If the value of Kc for the given reaction is smaller number than Energy of the products is likely to be less than the energy of the reactants ,because the value of Kc favour the products.
Reason:- because Kc is directly proportional to the concentration of products raised to power their stoichiometric coefficient.
