PLEASE EXPLAIN :) thank you.
Sodium bicarbonate undergoes thermal decomposition according to the reaction 2NaHCO3 (s) ?
Na2CO3(s) + CO2(g) + H2O(g). It is an endothermic reaction.
Which of the following will shift the equilibrium toward the reactant? Select all that apply.
adding Na2CO3
Solution
Increasing the pressure by reducing the volume,
Adding more CO 2 , decreasing the volume, Adding more H2O and removing NaHCO 3 are
favored conditions.
Reason is to favor above reaction towards reactant for above conditions that the forward reaction
is endothermic so if we give temperature the reaction favors forward reaction. If we increase
moles of gas and pressure the reaction forward towards less pressure side so in above reaction
gaseous molecules in products side so if we increase pressure the reaction favors towards
reactant side.
