Ī”H = Hf ā€“ Hi

Outra forma de calcular Ć© atravĆ©s da soma das entalpias em cada uma das reaƧƵes intermediĆ”rias. Independente do nĆŗmero e tipo das reaƧƵes.

Ī”H = Ī”H1 + Ī”H2

Nesse caso, as reaƧƵes sofridas sĆ£o endotĆ©rmicas, ou seja, hĆ” absorĆ§Ć£o de energia.

Ī”H1 Ć© a variaĆ§Ć£o de entalpia que acontece de A para B. Suponhamos que ela seja 122 kj.

Ī”H2 Ć© a variaĆ§Ć£o de entalpia que acontece de B para C. Suponhamos que ela seja 224 kj.

Ī”H3 Ć© a variaĆ§Ć£o de entalpia que acontece de A para C.

Assim, nos importa saber o valor de Ī”H3, pois corresponde Ć  variaĆ§Ć£o de entalpia da reaĆ§Ć£o de A para C.

Ī”H3 = Ī”H1 + Ī”H2

Ī”H3 = 122 kj + 224 kj

Ī”H3 = 346 kj

Ou Ī”H = Hf ā€“ Hi

Ī”H = 346 kj ā€“ 122 kj

Ī”H = 224 kj
