Problem 103

A mixture of N2(g) and H2(g) reacts in a closed container to form ammonia, NH3(g). The reaction ceases before either reactant has been totally consumed. At this stage 3.0 mol N2, 3.0 mol H2, and 3.0 mol NH3 are present. How many moles of N2 and H2 were present originally?

Step-by-Step Solution:

Answer Step 1 The mixture of nitrogen and hydrogen reacts to give ammonia in the habers process The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. The catalyst is actually slightly more complicated than pure iron. N2 3 H 22 NH 3 (H° = 91.8 kJ) => (H° = 45.8 kJ·mol ).1 The reaction stops before the total consumption of reactant or product takes place . 3 mol of NH3 ,3 moles of N2 ,3 moles of H2. This 3 moles of ammonia is formed from N2 , H2 .
