Balance each of the following examples of heterogeneous equilibria and write each reaction quotient, Qc:(a) NaHCO₃(s) ⇄ Na₂CO₃(s) + CO₂(g) + H₂O(g)

Respuesta :

When we balance the equation

NaHCO₃(s) ⇄ Na₂CO₃(s) + CO₂(g) + H₂O(g)

We will get

2NaHCO₃(s) ⇄ Na₂CO₃(s) + CO₂(g) + H₂O(g)

NaHCO₃(s) ⇄ Na₂CO₃(s) + CO₂(g) + H₂O(g)

We have to balance Na

2NaHCO₃(s) ⇄ Na₂CO₃(s) + CO₂(g) + H₂O(g)

Now the reaction is balance with

Na = 2, H = 2, C = 2, O = 6 in both the side.

The reaction quotient will be

    Qc = [product] / [reactant]

    Qc = [Na₂CO₃(s) + CO₂(g) + H₂O(g)] / [NaHCO₃(s)]
