Haber's process is used for the industrial production of ammonia. The process conditions at which maximum yield can be obtained, include 15-20mPa pressure, 400-500 degrees Celsius of the temperature, use of methane as a source of hydrogen, use of iron-based catalysts and combined with K2O, CaO, SiO2, and Al2O3<span>. Reuse of unreacted gases can lead to the achievement of 97% yield. </span>
C. Both NPN and PNP transistor operate in the same manner but with interchanged terminals and opposite directions of voltages and current. NPN received positive voltage to the terminal and connector. PNP receives positive voltage to the terminal, but negative to the connector.
