Questions and Answers

If a reaction is exothermic, what effect does a decrease in temperature have on the yield of the reaction?

  • Stops the reaction
  • Decreases yield of reaction (correct)
  • No effect on the yield of reaction
  • Increases yield of reaction
  • For gaseous reactions, what happens to the equilibrium if the pressure is increased?

  • Shifts to the side with fewer moles of gas (correct)
  • Shifts to the side with more moles of gas
  • Halts the reaction
  • No impact on equilibrium
  • In a reaction producing a larger volume of gas, what occurs when the pressure is increased?

  • Equilibrium shifts to the side with fewer moles of gas
  • No effect on equilibrium
  • Reaction stops
  • Equilibrium shifts to the side with more moles of gas (correct)
