Question

200m3 hydrogen gas are allowed to react with 250m3 of chlorine gas. Calculate the volume of unreacted gas and the volume of gaseous product formed. All the measurements are made at the same temperature and presure. What is the final volume of gaseous mixture?

Answer 1

Answer:

Gas laws

Gas laws describe the properties of gases. There are 3 laws:

Boyle's Law describes the indirect relationship between pressure (P) and volume (V); as pressure increases, volume decreases:

P_{1}V_{1}=P_{2}V_{2}

P_{1}V_{1}=P_{2}V_{2}

Charles' Law describes the direct relationship between volume (V) and temperature (T); as volume increases, temperature also increases:

\frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}

\frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}

Gay-Lussac's Law describes the direct relationship between pressure (P) and temperature (T); as pressure increases, temperature also increases:

\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}

\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}

These 3 laws combine to create the combined gas law, which describes the relationship between pressure, volume, and temperature:

\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}

\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}
