Linearity

[705903057]

What factors contribute to the non-linear relationship between reaction rate and reactant concentration in some chemical reactions, contrasting with the linear relationship observed in others? Specifically, why does the rate-concentration graph for a zeroth-order reaction appear linear, while for first or second-order reactions, it deviates from linearity?

Since the non linear relationship between the reaction rate and reactant concentration is influenced by reaction order, these are factors that affect them. Zero order reactions are independent of the concentration of the reactants which allows for a linear concentration graph. First order reactions are proportional to reactant concentration, which causes a curved rate concentration graph. Second order reactions are proportional to the square of the reactant's concentration or proportional to the product of 2 concentrations. This also procudes a graph that is non linear.
