Questions and Answers

What effect does a decrease in temperature have on an exothermic reaction?

  • Has no effect on the yield of reaction
  • Causes the reaction to stop
  • Increases yield of reaction
  • Decreases yield of reaction (correct)

    • In gaseous reactions, how does an increase in pressure affect the equilibrium?

  • Shifts to side with more moles of gas
  • Shifts to side with fewer moles of gas (correct)
  • No effect on equilibrium
  • Causes the reaction to reverse

    • For a gaseous reaction like N2 + 3H2 ⇌ 2NH3, what happens when pressure is increased?

  • Equilibrium shifts to the right side (correct)
  • More reactants are produced
  • Equilibrium remains unchanged
  • Equilibrium shifts to the left side
