Boiling the solution causes the equilibrium in the following reaction to shift to the . HCO3- H3O --> H2CO3 H2O

Right

Explanation:

The reaction of bicarbonate ion with acid is shown in the following equation;

HCO3- + H3O --> H2CO3 + H2O

This reaction is endothermic. This implies that energy must be absorbed from the surrounding as the reaction progresses.

Hence, when the solution is boiled, energy is supplied to the system in the form of heat and the forward reaction is favoured hence the equilibrium shifts to the right.
