Question

12. In an isolated container 1 mole of a liquid ,100 ml is present at 1 bar . If pressure is steeply taken to 100 bar find Δ H and Δ U for the process if volume is reduced by 1ml. Options: 1. 2O3(g) → 3O2(g) Δ H = ve, Δ S = +ve 2. Mg(s) + H2(g) → MgH2 Δ H = ve, Δ S = ve 3. Br2() → Br2(g) Δ H = +ve, Δ S = +ve 4. 2Ag() + 3N2(g) → 2AgN3 Δ H = +ve, Δ S = ve
