Versus concentration, the initial rate is plotted on the y-axis and the concentration of the reactant is plotted on the x-axis. This plot is used to determine the order of reaction with respect to the reactant whose concentration is being varied.
The Linewear Burk plot is a straight line when the reaction is first order with respect to the reactant being studied. The slope of the line is equal to the rate constant of the reaction. If the plot is not a straight line, it indicates that the reaction is not first order with respect to the reactant being studied.
To construct the Linewear Burk plot, a series of experiments are performed where the concentration of the reactant is varied while keeping the concentrations of other reactants constant. The initial rates of the reaction are measured for each experiment. These initial rates are then plotted against the corresponding reactant concentrations.
By analyzing the resulting plot, one can determine the order of the reaction with respect to the reactant being studied. If the plot is linear, the reaction is first order with respect to that reactant. If the plot is curved or does not follow a straight line, the reaction is not first order with respect to that reactant. The slope of the line in the linear region of the plot corresponds to the rate constant of the reaction.
