Commercial manufacturers produce nitric acid (HNO3) by the Ostwald process. The process requires three steps: 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g) 2NO(g) + O2(g) → 2NO2(g)
3NO2(g) + H2O (l) → 2HNO3(aq) + NO (g)
Begin with 37.0 kg of ammonia (NH3) and an unlimited supply of oxygen and water.
a) How many kilograms of oxygen gas will be consumed in the process?
b) How many kilograms of nitric acid will be produced? (i.e., the theoretical yield)
c) If the overall process normally has a percent yield of 83.0%, how many kilograms of nitric acid will actually be produced?

F ( x ) = ( 2 x² + 5 x - 12 ) / ( x + 4 )
x + 4 ≠ 0
x ≠ - 4 ( discontinuity at x = - 4)
f ( x ) = 0
2 x² + 5 x - 12 = 0
2 x² + 8 x - 3 x - 12 = 0
2 x ( x + 4 ) - 3 ( x + 4 ) = 0
( x + 4 ) ( 2 x - 3 ) = 0
x = - 4 ( not correct )
2 x - 3 = 0
2 x = 3
x = 3/2

A ) Discontinuity at ( - 4 , - 11 ), zero at ( 3/2, 0 ).
