When we balance the given equation

      C₂H₆(g) + O₂(g) ⇄ CO₂(g) + H₂O(g)

We will get

      2C₂H₆(g) + 7O₂(g) ⇄ 4CO₂(g) + 6H₂O(g)

Balancing the given equation

      C₂H₆(g) + O₂(g) ⇄ CO₂(g) + H₂O(g)

Balancing the number of O

      C₂H₆(g) + 5O₂(g) ⇄ 4CO₂(g) + 2H₂O(g)

Balancing the number of C and H

      2C₂H₆(g) + 7O₂(g) ⇄ 4CO₂(g) + 6H₂O(g)

We get balanced equation

      2C₂H₆(g) + 7O₂(g) ⇄ 4CO₂(g) + 6H₂O(g)

The reaction quotient will be

    Qc = [product] / [reactant]

     Qc ​= [CO₂(g) + H₂O(g)] / [C₂H₆(g) + O₂(g) ]
