In the reactions
(I) H2 (g) + 1/2O2(g) → H2O(l); ∆H = -286 KJ
(II) C(s) + O2g) → CO2 (g); ∆H = -406 KJ the equations imply that
- more heat is absorbed in (l)
- more heat is absorbed in (ll)
-
less heat is evolved in (l)
- reaction (ll) proceeds faster than (l)
- reaction (l) proceeds faster than (ll)
