Let’s balance the chemical equation for the gas-phase reaction of ethylene (C2H4) with hydrogen (H2) to form ethane (C2H6), excluding the palladium catalyst and including all physical states of matter.

1 answer

The balanced chemical equation for the reaction is:

C2H4 (g) + H2 (g) → C2H6 (g)

In this equation, 1 mole of ethylene reacts with 1 mole of hydrogen to form 1 mole of ethane.
