(a) Interpretation: The change in energy of the reverse reaction for the given reaction is to be determined. Concept Introduction: A biochemical reaction refers to a chemical reaction in which one molecule is transformed into different molecules present inside the cell of the living beings. These reactions occur via the help of certain biological enzymes that can alter the rate of the chemical reaction. The term hydrolysis refers to a chemical reaction which takes place when water ruptures one or more chemical bonds. In case of biological hydrolysis, the cleavage of biomolecules takes place in such a way that the larger molecules get break down to smaller ones.

Question

Suppose sodium sulfate has been gradually added to 100 mL of a solution containing calcium ions and strontium ions, both at 0.15 mol/L.
