Introduction to Le Chatelier's Principle

AP Chemistry· difficulty 3/5

CO + 2 H2 <-> CH3OH (dH < 0) stress shift add CO forward -> decrease V forward -> raise T reverse <- add catalyst no shift

Which row in the table is INCORRECT?

  • A

    None: all four rows shown are correct

    check_circle
  • B

    add CO row

  • C

    decrease V row

  • D

    add catalyst row

Explanation

Adding CO drives forward; decreasing V (3 mol -> 1 mol gas) drives forward; raising T for an exothermic reaction drives reverse; catalyst gives no net shift. All entries are correct.
