Question

A substance is combusted in the presence of oxygen within a bomb calorimeter. Using the diagram provided below, determine change in enthalpy and the direction (if any) of heat transfer.

Answer 1

The change in enthalpy is positive

∆H = +

Step-by-step explanation:

From the diagram above, we have a

substance combusted in presence of oxygen within a bomb calorimeter which implies that the reaction is endothermic (heat is conserved within the bomb calorimeter), this would make the enthalpy change to be positive.
