Sagot :
The balanced reaction equation is:
C2H2(g)+2H2(g)→C2H6(g)
The given volume of ethane product is:
vC2H6) = 7.5 L
We assume that this ethane was formed at constant temperature and pressure conditions. Therefore, we can relate volume values through the given stoichiometry. Assuming complete reaction, the ethane volume was formed from the given volume of hydrogen reactant:
v(H2) = 15 L
Acetylene and hydrogen react in a 1:2 ratio, so the required volume of acetylene is:
v(C2H2) = 7.5 L
Gas-Phase Chemical Reaction:
The volume of a gaseous species is highly sensitive to its temperature and pressure conditions. If these conditions are held constant, then the gas volume will vary proportionally to its molar quantity. If a given reaction system occurs in the gas phase at constant temperature and pressure conditions, then the behavior described here will apply to every gaseous species present. Therefore, the volume of each reactant will decrease over time, while the volume of each product will increase over time. The set of volume values will be related through the balanced stoichiometry.
