The rate of fchemical reaction depends on the nature of chemical reactions, because

Answer»

the threshold energy LEVEL differs from one reaction to another
some of the reactant are solid at room temperature
some of the REACTANTS are coloured
all

Solution :Difference in thershold energybarrier given difference values of energy of activation.
Also `K = Ae^(-E//RT)` and rate `= k ["reactant"]^n`
