Question

When nitrogen reacts with hydrogen to form ammonia, the equilibrium
murs contains 0.31 mol dm and 0.50 mol dm" of nitrogen and hydrogen
pecívely. If the K, is 0.50 mor’dm", what is the equilibrium concentration​

Answer 1

Answer:

Initial mole ratio N2:H2 is 1:3

At equilibrium, 50% of N2, H2 has reacted and equilibrium pressure is P
