Consider the Following Reaction

question 4

Multiple Choice

Consider the following reaction:
N₂ (g) + 3 H₂ (g) →2 NH₃ (g) What is the rate expression for each substance in this equation?

• A) Rate = D [N₂]/ D t = D [H₂]/ D t = D [NH₃]/ D t
• B) Rate = D [N₂]/ D t = D [H₂]/3 D t = D [NH₃]/2 D t
• C) Rate = -D [N₂]/ D t = -D [H₂]/3 D t = D [NH₃]/2 D t
• D) Rate = D [N₂]/ D t = 3 D [H₂]/ D t = - 2 D [NH₃]/ D t
• E) Rate = -D [N₂]/ D t = - 3 D [H₂]/ D t = 2 D [NH₃]/ D t
