What is the ΔG for the following reaction at 25°C?

SO3(g) + H2O(l) → H2SO4(l)

Given:

SO3(g):ΔG= –368 kJper mole

H2O(l):ΔG= –237 kJ per mole

H2SO4(l):ΔG= –689.9 kJ per mole


84.9 kJ


558.9 kJ


–84.9 kJ


–558.9 kJ

We write the equation as:

-368 + -237 = ΔH + -689.9

ΔH = 84.9 kJ/mol

When written outside of the reaction equation, its sign will be reversed.
Thus, ΔH = -84.9 kJ/mol

The third option is correct.
