One of the steps in the commercial process for converting
ammonia to nitric acid involves the conversion of NH3 to NO, as
shown below.
4 NH3(g) + 5 O2(g) 4 NO(g) + 6 H2O(g)
In a certain experiment, 2.50 g of NH3 reacts with 4.10 g of
O2.
(a) Which reactant is the limiting reactant? NH3 O2
(b) How many grams of NO form?
(c) How much of the excess reactant remains after the limiting
reactant is completely consumed?
