3 Multiple choice questions

  1. (chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected
  2. (chemistry) the ratio of concentrations when equilibrium is reached in a reversible reaction (when the rate of the forward reaction equals the rate of the reverse reaction)
  3. (Q) the value that is obtained when concentrations of reactants and products are inserted into the equilibrium expression. If the concentrations are equilibrium concentrations, Q=K, otherwise Q can't equal K.

3 True/False questions

  1. chemical equilibriuma state of balance in which the rates of the forward and reverse reactions are equal; no net change in the amount of reactants and products occurs in the chemical system


  2. homogeneous equilibriaan equilibrium system in which all reactants and products are in the same state


  3. heterogeneous equilibriaan equilibrium involving reactants and/or products in more than one state
