which of the following statements about K of 3.5 calculated for a specific chemical reaction at equilibrium is incorrect? A: It was calculated by dividing the products by that of the reactants B: it indicates that one side of the reaction has most of the matter present C: it is an evaluation of the extent of the two chemical reactions involved: the forward and the reverse reactions D: a K of 3.5 indicates that a catalyst will push the reaction to the right

Which of the following statements is true about chemical equilibrium? Select all that apply. At chemical equilibrium, the reactants have been completely consumed. At chemical equilibrium, both reactions stop completely. At chemical equilibrium, the concentrations of the species involved in the reaction stay constant (in the absence of an external perturbation). At chemical equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.
1. Which of the following is true for a chemical reaction at equilibrium? only the forward reaction stops only the reverse reaction stops both the forward and reverse reactions stop the rate constants for the forward and reverse reactions are equal the rates of the forward and reverse reactions are equal 2. A chemical equilibrium may be established by starting a reaction with reactants only. d. any quantities of reactants and products. products only. e. all the above equal quantities...
QUESTION 4 Which of the following statements about a system at chemical equilibrium is true? There are no more reactants left. The reverse reaction has a faster rate than the forward reaction. The forward reaction rate is equal to the reverse reaction rate. The forward and reverse reactions both stop. The forward reaction has a faster rate than the reverse reaction.
QUESTION 4 Which of the following statements about a system at chemical equilibrium is true? The reverse reaction has a faster rate than the forward reaction. The forward reaction rate is equal to the reverse reaction rate. There are no more reactants left. The forward reaction has a faster rate than the reverse reaction. The forward and reverse reactions both stop.
Which of the following statements is/are CORRECT? For a chemical system at equilibrium, the forward and reverse rates of reaction are equal. For a chemical system at equilibrium, the concentrations of products divided by the concentrations of reactants equals one. For a chemical system, if the reaction quotient (Q) is less than K, reactant must be converted to products to reach equilibrium.

Keg for a reaction written in reverse is the reciprocal of the key for the forward reaction A reaction quotient (Q) larger than Keq means that the reaction will shift toward reactants Chemical equilibrium indicates that reactants and products are present in...
