The reaction is a hydrogenation reaction of an alkene, and its equation is:
C₂H₄(g) + H₂(g) → C₂H₆(g)
Therefore, this reaction can be sped up just as any other irreversible reaction may have its rate increased, by increasing temperature and pressure to increase the effective collisions of molecules.
The answer is 4. Hope it helps!
- The atomic mass of hydrogen is 1.00794 g/mol.
- The atomic mass of sulfur is 32.06 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
So, the total atomic mass is
