Answer:

Explanation:

From the question, we know that;

2H+H^+ ----->H^3+, ∆H°=-849 kilojoule per mole --------------(1).

H2 --------------->2H, DH° = 436.6 kilojoule per mole ---------------(2).

Adding the equation (1) and equation (2) above gives another equation of reaction, which is;

H2 + H^+ --------------> H^3+ --------------------------------------------(3)

∆H° = [-(849) - (+436.4)] kilojoule per mole.

∆H°=[-(849) - 436.4] kilojoule per mole....

∆H= - 1,285.4 kilojoule per mole
