摘要 以纳米氧化镍与硫酸氢钠溶液为反应体系,研究了纳米氧化镍的粒度对其化学反应平衡常数的影响规律,讨论了平衡常数与粒度间的关系。研究结果表明:粒度对纳米氧化镍与硫酸氢钠溶液反应的平衡常数有显著的影响,随着纳米氧化镍粒度的减小,化学反应的平衡常数增大;并且其平衡常数的对数与其粒径的倒数呈线性关系;实验结果与热力学理论分析结果一致。 With the reaction of nano-NiO and NaHSO4 solution as a model reaction system,the effect of particle size on the chemical equilibrium constant was studied,the relation between the equilibrium constant and particle size was discussed in this paper.The results show that there is remarkable effect of the particle size of nano-NiO on the equilibrium constant.The equilibrium constant increases with decreasing size of the reactant,and a linear relationship exists between logarithms of the equilibrium constant and the reciprocal of the particle size.The experimental results are in agreement with theoretical analysis of the thermodynamics.
