Ethyne or acetylene can be hydrogenated to change from the triple bonded C2H2 to the double-bonded C2H4. Adding hydrogens in org
anic chemistry is called reduction. Adding and removing hydrogens are important steps in chemical manufacturing. Calculate the value of ΔS° for the catalytic hydrogenation of acetylene to ethene,
C2H2 (g) + H2 (g) --> C2H4 (g)
A. +18.6 J/mol K
B. -18.6 J/mol K
C. -112.0 J/mol K
D. +112.0 J/mol K
C2H2 (g) + H2 (g) --> C2H4 (g)
A. +18.6 J/mol K
B. -18.6 J/mol K
C. -112.0 J/mol K
D. +112.0 J/mol K

Answer:- 1.62 moles
Solution:- At constant temperature and pressure, volume is directly proportional to the moles of the gas.
from given data, = 5.17 L,
= 1.05 moles
= 8.00 L,
= ?
Let's plug in the values in the formula:
On cross multiply:
= 1.62 moles
So, now the toy contains 1.62 moles of the air.
