Final answer:
The reaction order is a fixed property of a chemical reaction that describes the dependence of the reaction rate on the concentration of reactants and does not change with temperature.
Step-by-step explanation:
The reaction order of a reaction is not affected directly by temperature. Temperature can impact factors such as the reaction rate and the rate constant.
According to the Arrhenius equation, the rate constant (k) increases with an increase in temperature because a higher temperature means a greater fraction of molecules have enough energy to overcome the activation barrier, accelerating the reaction.
However, the reaction order is an inherent characteristic of the reaction that describes the relationships between the concentrations of reactants and the rate of the reaction and does not change with temperature.
