N2 + 3H2 ---> 2NH3 What volume of hydrogen is necessary to react with five liters of nitrogen to produce ammonia? (Assume constant temperature and pressure.)
N2 + 3H2 ---> 2NH3 , as per this equation, 1 volume of Nitrogen , needs 3 volumes of Hydrogen. The reaction produces two volumes of ammonia.
Let us write this as equation;
1 volume of Nitrogen3 volume of Hydrogen (a)
If we start with 5 L of Nitrogen , X volumes of Hydrogen will be needed.
Let us write this as equation;
5 L of NitrogenX L of Hydrogen (b)
equate (a) and (b)
13 = 5X
cross multiply 1⋅X = 3⋅5 , X=15 L
2CO + O2 ---> 2CO2 How many liters of carbon dioxide are produced if 75 liters of carbon monoxide are burned in oxygen? How many liters of oxygen are necessary?
As per this equation, 2 volumes of Carbon Monoxide, needs 1 volume of Oxygen. The reaction produces two volumes of Carbon dioxide.
Let us write this as equation;
2 volume of Carbon Monoxide2 volumes of Carbon Dioxide (a)
If we start with 75 L of Carbon monoxide , X volumes of carbon dioxide will be produced.
Let us write this as equation;
75 L of COX L of CO2 (b)
equate (a) and (b)
22 = 75X
cross multiply 2⋅X = 2⋅75 , X= 75 L
2 volume of Carbon Monoxide1 volumes of Oxygen (a)
If we start with 75 L of Carbon Monoxide , X volumes of Oxygen will be needed.
75 L of COX L of O2 (b)
equate (a) and (b)
21= 75X
2⋅X = 75⋅1
2X =75
X= 37.5 L
