Question 12(multiple choice worth 1 points) (07.01 lc) which of the following is a characteristic of an endothermic chemical reaction? the energy of the reactants is higher than the energy of the products. the amount of energy released is equal to the activation energy. the overall enthalpy of the system increases during the change. energy is released into the surroundings during this change. question 13(multiple choice worth 1 points) (07.05 mc) the volume of a reaction vessel with gaseous reactants is lowered to one-fourth of its original volume. what will happen to the rate of the reaction? it will increase because the concentration of the reactants increases. it will decrease because the concentration of the reactants decreases. it will increase because the gaseous particles are moved farther apart. it will decrease because the gaseous particles are brought closer together. question 14(multiple choice worth 1 points) (07.06 mc) the equilibrium constant k for a certain reversible reaction is 1.41 × 103. which of the following is true for the reaction? the reverse reaction is more favorable than the forward reaction. the reverse reaction takes place at a much faster rate than the forward reaction. the equilibrium reaction mixture will have a very high concentration of reactants. the equilibrium reaction mixture will have a very high concentration of products. question 15(multiple choice worth 1 points) (07.07 mc) a reaction mixture is at equilibrium. what happens when the amount of one of the reactants is lowered? the amount of the product increases. the rate of reverse reaction increases. the amount of the other reactant is also lowered. the equilibrium state is lost and cannot be restored.
