sat2普林斯顿化学题 reaction rate can be increased by increasing the surface area of reactants144页18题为什么选项A不对:Ca(aq) + CO3(aq) = CaCO3(S) (不会打右上角脚标因此省略)增大反应物面积一定要是固体和液体吗,溶液和溶液不行吗?
The model implies that electrode impedances depend strongly on the perovskite surface area available for reaction and on the structure and ionic conductivity of the porous electrolyte scaffold. These predictions were experimentally verified on Acknowledgements This work was funded by the U.S. Department...

Comprehensive research results show that the fouling rate is mainly affected by mass transfer at low flow rate while it is mainly affected by surface reaction rate at high flow rate[47,48]. Ahfir et al.[49]explored the transport and deposition rates of suspended particles in saturated porous ...
The net rate of production of a component is an experimentally observed characteristic. It is the change of the number of moles of a component per unit volume of reactor (or catalyst surface, volume, or mass) per unit time. The reaction rate r can be introduced only after a reaction ...
