ENTHALPY HELP URGENT PLEASEEEE (1 Viewer)

What are the enthalpy for the following three equations, I need it urgently!!!

Dissolution: CO2(g) ⇌ CO2(aq)


Hydrolysis: CO2(aq) + H2O(l) ⇌ H2CO3(aq)

Ionisation: H2CO3(aq) ⇌ HCO3-(aq) + H+(aq)

Ok so for the dissolution , the standard enthalpy is -8.647 kJ mol-1 (source: carbon dioxide - data page wikipedia as enthalphy of dissolution is negative of enthalpy of fusion). For the other two i suggest search enthalpy for the carbonic acid equilibrium (as you are saying it is urgent) but if i find it I will post.

Hydrolysis - +22.0 kJ mol-1
Ionisation - too tired but i found the enthalpy of formations for hco3 and h2co3 and h+ ion (enthalpy of dissolution for h(g)) so use the yr 11 stuff to find out

Yep I just realised. If no one responds you can just bump it. People probably just didn’t see it.
