Question

Sample Problem 5 For the reaction, N2 (g) + 3 H2(g) is 2 NH3(g), the partial pressures of N, and H, are 0.80 and 0.40 atmosphere respectively at equilibrium. The total pressure of the system is
2.80 atmospheres. What is K, for the above reaction ?
pls give the correct answer with explanation ​

Answer 1

Answer:

kp=50

Explanation:

N2

2 +3H

3 ⇌2NH

Total pressure = (partial pressure of N 2)+ ( partial pressure of H2) + ( partial pressure of NH 3 )

2.8 atm=0.8 atm+0.4 atm+x atm

x=1.6 atm

kp= P N2 xP x22P NH 32= 0.8×(0.4) 3(1.6) 2

= 8×4 3 ×10 −416 2 ×10 −2

kp =50
