The decomposition of ammonia gas (NH3) leads to the production of N2 gas and H2 gas. A chemist adds 4.0 mol of ammonia gas to a 2.0 L sealed, rigid container and heats it. It has been found that at equilibrium the number of moles of ammonia gas is 2.0 in the same 2.0 L container. Determine the equilibrium concentration of N2 and H2 gas,
