Interpretation:
The given reaction occurs in single step or not has to be explained.
Concept Introduction:
The relationship between rate and initial concentration of reactant is described by rate law. It is an experimentally determined equation and cannot be found out theoretically from the stoichiometry of the reactants and products.
Where,
If one or two species react directly to form products through a single step then it is called an elementary reaction or a single step reaction. Multistep reaction involves the combination of two or more elementary steps.

- At 500 K in the presence of a copper surface, ethanol decomposes according to the equation C2H5OH(g)CH3CHO(g)+H2(g) The pressure of C2H5OH was measured as a function of time and the following data were obtained: Time(s) PC2H5OH(torr) 0 250. 100. 237 200. 224 300. 211 400. 198 500. 185 Since the pressure of a gas is directly proportional to the concentration of gas, we can express the rate law for a gaseous reaction in terms of partial pressures. Using the above data, deduce the rate law, the integrated rate law, and the value of the rate constant, all in terms of pressure units in atm and time in seconds. Predict the pressure of C2H5OH after 900. s from the start of the reaction. (Hint: To determine the order of the reaction with respect to C2H5OH, compare how the pressure of C2H5OH decreases with each time listing.)arrow_forwardNitryl fluoride is an explosive compound that can be made by oxidizing nitrogen dioxide with fluorine: 2 NO2(g) + F2(g) → 2 NO2F(g) Several kinetics experiments, all done at the same temperature and involving formation of nitryl fluoride, are summarized in this table: Write the rate law for the reaction.

If a reaction is zero order, what effect does [A] have on the initial rate of a reaction?arrow_forward
- Candle wax is a mixture of hydrocarbons. In the reaction of oxygen with candle w ax in Figure 11.2, the rate of consumption of oxygen decreased with time after the flask was covered, and eventually' the flame went out. From the perspective of the kinetic-molecular theory, describe what is happening in the flask. FIGURE 11.2 When a candle burns in a closed container, the flame will diminish and eventually go out. As the amount of oxygen present decreases, the rate of combustion will also decrease. Eventually, the rate of combustion is no longer sufficient to sustain the flame even though there is still some oxygen present in the vessel.arrow_forwardThe thermal decomposition of nitryl chloride, NO2Cl, 2NO2Cl(g)2NO2(g)+Cl2(g) is thought to occur by the mechanism shown in the following equations: NO2Clk1NO2+Cl(slowstep)NO2Cl+Clk2NO2+Cl2(faststep) What rate law is predicted by this mechanism?arrow_forwardHydrogen iodide decomposes when heated, forming H2(g) and I2(g).
