1、

ClF3的物质的量 n = pV/RT = 250/760*101325 × (2.5/1000) ÷ 8.314 ÷ 293 mol = 0.0342 mol

NiO的物质的量 = 0.0342 * 6 / 4 mol = 0.0513 mol

NiO的质量 = 0.0513 * (59+16) g = 3.85 g

2、

生成Cl2的物质的量 = 0.0342 * 2 / 4 = 0.0171 mol

Cl2的分压 p = nRT/V = 0.0171×8.314×293 ÷ (2.5/1000) / 101325*760 = 125.0 mmHg

生成O2的物质的量 = 0.0342 * 3 / 4 = 0.0257 mol

Cl2的分压 p = nRT/V = 0.0257×8.314×293 ÷ (2.5/1000) / 101325*760 = 187.8mmHg

总压 = 125.0+187.7 = 312.7 mmHg
