$H_{2} (g) + \frac{1}{2} O_{2} (g) ⟶ H_{2} O (g) Δ H = - 50 K$ cal at $2 5^{\circ} C$

Calculate of ΔH (in K cal) at 65°C. Assume gases behave like an ideal gas.

[Given: R = 2 Cal/ mol/ K]

Answer:

-50

Solution:

ΔH is nearly constant with temperature for ideal gases, so ΔH at 65°C is approximately -50 Kcal.
