Do the equilibrium concentrations change?

If we change the initial concentrations, do the equilibrium concentrations change?

Make sure that K = 0.25. Place 1 mole of N2 and 1 mole of H2 into the reaction vessel and press "equilibrate". Write down the number of moles of each substance that you have at equilibrium. Convert from number of moles to molarity.

Plug the concentrations of N2, H2, and NH3 into the equilibrium constant expression. Verify that this expression gives the value of Kc that you expect.
