When we balance this equation and the reaction quotient
KNO₃(s) ⇄ KNO₂(s) + O₂(g)
We will get
2KNO₃(s) ⇄ 2KNO₂(s) + O₂(g)
Balancing this equation
KNO₃(s) ⇄ KNO₂(s) + O₂(g)
We have to balance the number of O
2KNO₃(s) ⇄ KNO₂(s) + O₂(g)
We have to balance the number of K and N
2KNO₃(s) ⇄ 2KNO₂(s) + O₂(g)
We will get balanced equation
2KNO₃(s) ⇄ 2KNO₂(s) + O₂(g)
The reaction quotient will be
Qc = [product] / [reactant]
Qc = [KNO₂(s) + O₂(g)] / [ KNO₃(s)]
