Questions and Answers

What will happen if a larger quantity of B and C is added to the reaction?

  • It will decrease the yield of product D.
  • It will not change the yield of product D. (correct)
  • It will cause the reaction to stop.
  • It will increase the yield of product D.

    • What is the effect of higher temperatures on products D, the intermediate, and E?

  • Higher temperatures increase the proportions of D.
  • Higher temperatures increase the proportions of product E. (correct)
  • Higher temperatures increase the proportions of the intermediate.
  • Higher temperatures have no effect on any of the products.

    • What occurs when a strong base is added to the reaction involving E and acid?

  • The reaction is reversed to yield D and the intermediate. (correct)
  • The reaction proceeds to form more product E.
  • There is no effect on the reaction.
  • The reaction is halted entirely.

    Chemical Reaction Notes

    • A chemical process involving four reactants (A, B, C, and acid) yields product D
    • The process then includes two subsequent reactions, with D as the starting material, and E as the ultimate product
    • The formation of D is independent of the amounts of B and C used, suggesting these reactants play only a catalytic role
    • The intermediate product coexists with D and E, demonstrating a dynamic equilibrium
    • Increasing temperature favors the formation of E, indicating that the reaction is endothermic
    • The final reaction (E + acid --> X) is reversible, and the addition of a strong base shifts the equilibrium towards the reactants by neutralizing the acid
