For a dimerization reaction, 2A(g) → A₂(g), at 298 K, ∆Uᶱ = -20 kJmol⁻¹, ∆Sᶱ = -30 JK⁻¹mol⁻¹, then the ∆Gᶱ will be J.

2 A (g) → A? (g)
Δn_g = 1 - 2
Δn_g = 1
ΔH = ΔU + Δn_gRT
ΔH = -20 * 10³ + (-1)8.31 * 298
ΔH = -22477.572 J mol? ¹
ΔG = ΔH - TΔS
ΔG = -22477.572 - (-30)298 = -22477.572 + 8940
ΔG = -13537.57 J mol? ¹
