In which order the rate of reaction does not depend on the concentration of reactant

Consider two reactions, one that is first order and one that is second order. Which best describes the effect on the reaction rates by INCREASING the concentration of all reactants?

Rate constant of a zero order reaction does not depend upon the concentration of thereactant

If the rates of reaction are R1 and R2 at concentrations C1 and C2 of a reactant respectively, the order of reaction n (assuming that the concentrations of all other reactants and T remains constant) with respect to that of reactant is given by

How does the rate law equation effectively describe the relationship between the rate of a chemical reaction and the concentration of reactants?

The rate constant of a first order reaction is 4×10−3sec−1 .At a reactant concentration of 0.02 M, the rate of reaction would be:
