1. Ammonia can be produced by the Haber Process at 450 K:
N2 (g) + 2 H2 (g) → N2H4 (g)
I start with 2 atm of N2 and 2 atm of H2 in a 2 L flask. When equilibrium has been established, there is 1.25 atm of N2 remaining.
What is the Kp for this reaction at 450 K?
Homework Answers
Kp=(1.25 atm)/[2 atm*(2 atm)^2]=0.3125
