(B) ,  kJ mol

Choose the correct statement:

Canvas Classes · Accepted Answer

Strategy:
 Analyze the experimental data to differentiate between heat of solution and the effect of concentration. The heat of solution is the enthalpy change when a solute is dissolved in a solvent.

Step 1: Evaluate statement (b)
The data shows that dissolving  of  gas in  of water releases , whereas  in  of water releases . This clearly demonstrates that the enthalpy change (heat of solution) varies with the amount of solvent used.
