Answer 2

Calculating the Volume of Hydrogen Gas

When 1 liter of ethane undergoes dehydrogenation to form ethylene, the volume of hydrogen gas formed can be calculated using the stoichiometry of the reaction. The balanced chemical equation for the dehydrogenation of ethane to form ethylene is as follows:

C2H6 → C2H4 + H2

According to the stoichiometry of the reaction, for every 1 mole of ethane reacted, 1 mole of ethylene and 1 mole of hydrogen gas are formed.

To calculate the volume of hydrogen gas formed, we can use the ideal gas law, which states that at standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters.

Therefore, the volume of hydrogen gas formed when 1 liter of ethane is dehydrogenated to form ethylene is 2 liters.

This calculation is based on the stoichiometry of the reaction and the ideal gas law Therefore, the correct answer is b) 2 liters.
