The Ostwald process is used commercially to produce nitric acid, which is, in turn, used in many modern chemical processes. In the first step of the Ostwald process, ammonia is reacted with oxygen gas to produce nitric oxide and water. What is the maximum mass of H2O that can be produced by combining 57.7 g of each reactant?

what is the maximum mass of H2O that can be produced by combining 57.7g of each reactant?

4NH + 5O2 --------> 4NO + 6H2O

__________ g H2O

Solutions

Expert Solution

4NH3   +   5O2    ----------------> 4NO    +    6H2O

68 g       160 g                           120 g         108 g     

57.7         57.7                                                  ??

here limiting reagent is O2. so product formed based on that.

160 g O2 --------------->   108 g of H2O

57.7 g O2 --------------->   ??

mass of H2O produced = 57.7 x 108 / 160 = 39.0 g

mass of H2O = 39.0 g
