Catalysts affect reaction rates, but do not change either the equilibrium or the spontaneity of a reaction. True or False.
The choices are: Reversible reaction, Le Châtelier’s principle, and Chemical equilibrium
3. Assume that the following exothermic reaction is at equilibrium H 2(g) + I 2(g) = 2 HI(g) Tell whether the position of equilibrium will shift to the right or the left if we: Remove some HI Add some I2 Increase the pressure Increase the temperature Add a catalyst
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
Question 20 Which statement best describes general equilibrium? Equilibrium is reached when the reaction stops. 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.
Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. At equilibrium the speed of a reaction equals its rate constant. At equilibrium concentrations of reactants and products stay constant. At equilibrium the reverse rate equals zero. ☐ At equilibrium the rate of change of product concentration is zero. As a reaction proceeds backwards toward equilibrium the product concentrations drop.
4. What does a bi-directional arrow tell you about a chemical reaction? The reaction happens only once The reaction happens more than once The reaction is able to reverse O The reaction is at equilibrium
true or false? If a reversible reaction at equilibrium is exothermic and the tempature is raised the concentration of the products will increase
