Gas volume-Gas Volume Calculations

Topic Content:

In this type of reaction, only volumes of reactants and products are involved.

Example 6.5.1:

40 cm³ of nitrogen gas reacts with 60 cm³ of hydrogen gas to form ammonia gas. Calculate the volume of unused and the volume of ammonia formed at the same temperature and pressure.

Solution

From Gay Lussac’s Law

1 cm³ of N₂ reacts with 3 cm³ of H₂ to produce 2 cm³ of NH_3.

Therefore 20 cm³ of
