How does adding more product to an equilibrium mixture immediately affect the reaction rates?
Which of the following is true about a system at dynamic equilibrium?
Which of the following is an accurate short Le Chatelier statement?
A student carries out a reversible gas reaction in a closed container and increases the container temperature. Immediately the concentration of product increases but later drops to a lower value than before the temperature change. Is this possible?
A certain reversible reaction is endothermic in the forward direction. When the system is cooled, the equilibrium will:
A reversible gas reaction has fewer moles of gas on the product side than on the reactant side. Increasing the pressure (by decreasing the container volume) will:
Which description best differentiates reaction rate and equilibrium yield?
Hydrogen and iodine reach a dynamic equilibrium: 2HI ? H2 + I2. Which of the following best describes a dynamic equilibrium?
Which statement about catalysts is correct?
When gases A and B react to equilibrium A ? B and the equilibrium is exothermic forward, adding heat is equivalent to:
A reversible reaction reached equilibrium in a sealed vessel. Which of these would definitely change the equilibrium constant K at that temperature?
