Answer to Question #289600 in Physical Chemistry for Laura

Question

Si se agrega bicarbonato de sodio adicional a la reacción presentada a continuación

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

¿qué sucederá con la reacción general?

Answer 1

Heating solid sodium bicarbonate in a closed vessel establishes the following equilibrium.

$2NaHCO_{3(s)}\leftrightharpoons\>Na_2CO_{3(s)}+H_2O_{(g)}+CO_{2(g)}$

Adding more sodium bicarbonate will shift the equilibrium to the right yielding more of $Na_2CO_3,H_2O$ and $CO_2$
