Which of the following is true for chemical equilibrium? I. Forward and reverse reaction rates are equalII. Equilibrium can be achieved from either directionIII. Reaction rates and therefore equilibrium is temperature-dependent. a I only b I and II only c II and III only d I, II and III
For any reversible reaction containing a double arrow such as: Reactants ⟷⟷ Products the statement "equilibrium shifts to the right" means: Group of answer choices; - The reaction can only go in the forward direction. - The reaction can only go in the reverse direction. - A stress will cause a portion of reactants to disappear and some additional products to appear. - A stress will cause a portion of products to disappear and some additional reactants to appear
23. What happens when a chemical reaction reaches equilibrium? The amounts of reactants and products remain constant because the reaction stops. The reaction stops because the concentration of reactants is too low to sustain it. The reaction reverses so some of the products are converted back into reactants. The rate of the forward reaction is the same as the rate of the reverse reaction. PREVIOUS 23 of 25 NEXT REVIEW
Which statement best describes general equilibrium? O Equilibrium is reached when the reaction stops. O There is only one set of equilibrium concentrations that equals the Kc value. At equilibrium, the rate of the forward reaction is the same as the rate of the reverse reaction. At equilibrium, the total concentration of products equals the total concentration of reactants.
