Practice AP Chemistry Fundamental Equilibrium Concepts in the app →The constant value of the reaction quotient shown by a system at equilibrium is called the:An equilibrium in which every reactant and product is in the same phase is described as:For a gas-phase equilibrium, the constant can be written using concentrations or:A reaction with a very large equilibrium constant reaches equilibrium when:A change in conditions that upsets the balance of forward and reverse rates is called a:If the reaction quotient is greater than the equilibrium constant, the reaction will proceed:Adding reactant to a system at equilibrium makes the quotient smaller than K, so the equilibrium:Adding hydrogen or iodine to a hydrogen iodide equilibrium increases the rate of:Removing hydrogen iodide from its equilibrium mixture leaves the concentrations of all three species:Multiplying every stoichiometric coefficient in an equation by a factor changes K:Changing the volume of a gas-phase equilibrium changes the concentrations of:A reaction quotient equation using absolute concentrations rather than relative values is:Reactions differ from many physical processes in that they may proceed:Adding 0.10 mol of nitrogen dioxide to a 1.0 litre flask at 25 degrees Celsius left equilibrium concentrationsMany real systems involve coupled equilibria, meaning two reactions that share:The reaction quotient is useful during a reaction because its value:
