Question
Which of the following species would be considered an intermediate?_____ In a heterogeneous reaction, why are the concentrations of solids not included in the equilibrium constant expression? _____ The surface area is more important than the concentration. The concentration of the solid does not vary. Solids do not take part in chemical reactions. Reactions involving solids do not go to equilibrium. ____ In a chemical system at equilibrium, ______ the chemical reactions have all stripped. the forward and reverse reactions occur at equal rate. all of the reactants have been converted to products. the reactants and products have stopped interacting. When a system is at equilibrium, which of the following is true? _____ The concentrations of reactants and products do not appear to change. The forward and reverse reactions have stopped. The concentrations of the reactants and products arc equal The forward and reverse reactions have rates that are equal to zero. How can the reaction quotient be used to predict the direction of chemical reactions? ____ If the reaction quotient is greater than K, reactants are converted to products. If the reaction quotient is less than K, products are converted to reactants. If the reaction quotient is equal to K, reactants are converted to products. If the reaction quotient is less than K, reactants are converted to products. According to lessthanorequalto Chatelier's principle, If a stress is applied to a system at equilibrium, how will the system respond? The system will respond to relieve the applied stress. The system will react to form more of the products The system will react to maximize the effect of the stress. The system will not change in composition.Explanation / Answer
5) Part B) HOOBr is considered as an intermediate because it is forming in the slowest first step of the reaction.
6) B) The concentraton of the solid does not vary as solids have there fixed concentration in terms of density which is constant.
7) B) Th forward and reverse reactions occur at equal rate.
8) D) The forward and reverse reactions have rates that are equal to zero.
9) D) If reaction quotient is less than K, the reactants are converted to products.
10) A) The system will respond to relieve the applied stress because it will tend to minimize that stress in an opposite manner.
