Worksheet: Converting between Reaction Quotients and Pressures

Q1:

Consider the reaction N + O 2 N O 2 2 ( ) ( ) ( ) g g g . The equilibrium constant for this reaction has a value of 2 . 5 × 1 0 3 at a temperature of 2 4 0 0 K. What would be the partial pressure of N O in an equilibrium mixture that is at 2 4 0 0 K and contains N 2 ( ) g at a partial pressure of 0.1 bar and O 2 ( ) g at a partial pressure of 0.1 bar?

  • A 0.2 bar
  • B 2 . 5 × 1 0 5 bar
  • C There is not enough information provided to answer this question.
  • D 5 . 0 × 1 0 3 bar
