Question

For the gaseous reaction 3H2+ n2 gives 2nh3 the equilibrium pressures of h2 and n2 are 0.4atm and. 8atm respectively. The total pressure of the equilibrium system is 2.8atm. the value of kp is

Answer 1

i this photo answer is written

Answer 2

the answer is 50

total pressure= partial pressure of reactants + partial pressure of products

2.8 = 0.4 + 0.8 + x

x= 1.6 atm

kp = 1.6^2/0.4^3*0.8

kp= 50
