The question compares the enthrall change of ethanoate acid and hydrochloride acid.
The MS States:
Ethanoate acid is a weak acid that partially dissociates
It's dissociation is endothermic
Therefore lowering the heat given out by the reaction
Can anyone explain why it's dissociation in endothermic pls??
Why is ethanoate acids dissociation endothermic? OCR Question Watch

Bond dissociation is endothermic always. Bond formation is exothermic always.

HCL is a strong acid so it would fully dissociate. This is also an endothermic reaction. Similarly when bonds are broken producing H+ ions in the case of ethanoic acids partial dissociation we have an endothermic reaction.
