In Haber process 30L of  dihydrogen and 30L of dinitrogen were taken for reaction which yielded only 50% of the expected product. What will be the composition of gasesous mixture under the a fore said condition in the end?

(1) 20L ammonia, 10L nitrogen, 30L hydrogen

(2) 20L ammonia, 25L nitrogen, 15L hydrogen

(3) 20L ammonia, 20L nitrogen, 20L hydrogen

(4) 10L ammonia, 25L nitrogen, 15L hydrogen
