To determine the reaction order from concentration and time data, one can use the method of initial rates. By comparing the initial rates of the reaction at different concentrations of reactants, the reaction order can be determined based on how the rate changes with respect to the concentration of each reactant.

How can one determine the order of reaction from a given table of data?
To determine the order of reaction from a given table of data, you can look at how the rate of the reaction changes with the concentration of the reactants. If the rate is directly proportional to the concentration of a reactant, the reaction is first order with respect to that reactant. If the rate is proportional to the square of the concentration, the reaction is second order. By analyzing the data and observing how the rate changes with different concentrations, you can determine the order of the reaction.
How can one determine the order of reaction by utilizing concentration and time data?
To determine the order of reaction using concentration and time data, one can plot the natural logarithm of the concentration of the reactant against time. The slope of the resulting graph will indicate the order of the reaction. If the slope is constant, the reaction is first order; if the slope doubles, the reaction is second order; and if the slope triples, the reaction is third order.
How can one determine the reaction order from a table of experimental data?
To determine the reaction order from a table of experimental data, you can plot the concentration of the reactant versus time for each experiment. The reaction order is determined by the slope of the line on the graph. If the slope is constant, the reaction is first order. If the slope doubles, the reaction is second order. If the slope triples, the reaction is third order.
The decomposition reaction of ammonia gas on platinum surface has a rate constant k equals 2.510-4 mol l-1s-1 what is the order of the reaction?
The rate constant is not indicative of the order of the reaction. To determine the order of the reaction, experimental data (such as concentration vs. rate data) is needed. The order of the reaction can be found by examining how changes in reactant concentrations affect the rate of the reaction.
How is order of reaction determined graphically?
The order of a reaction can be determined graphically by analyzing concentration versus time data. For a first-order reaction, plotting ln(concentration) versus time should give a straight line. For a second-order reaction, plotting 1/concentration versus time should give a straight line. The slope of the line in these graphs reveals the order of the reaction.
