Calculate ΔH^o_R and ΔU^o_R at 298.15 K for the following reactions:

a. 4NH₃(g) + 6NO(g) → 5N₂(g) + 6H₂O(g)

b. 2NO(g) + O₂(g) → 2NO₂(g)

c. TiCl₄ (l) + 2H₂O(l) → TiO₂ (s) + 4HCl(g)

d. 2NaOH(aq) + H₂SO₄(aq) → Na₂SO₄(aq) + 2H₂O(l). Assume complete dissociation of NaOH, H₂SO₄, and Na₂SO₄.

e. CH₄(g) + H₂O(g) → CO(g) + 3H₂ (g)

f. CH₃OH(g) + CO(g) → CH₃COOH(l)
