Analytical chemistry 6.2:Rate of redox reactions cC=1.44V=0.56V △E>0.4V K'=10298 But the rate of the reaction is very slow.There is no relationship between o and rates because the two are different aspects of a reaction. The factors that affect the rate of a reaction are as follows 1.The concentration of the reactants Generally speaking,the reaction rate increases with increasing the concentration of the reactant. 2025/4/6
