Interpretation: The concentration of
Concept Introduction:
The
The raise in molar concentration of product of a reaction per unit time or decrease in molarity of reactant per unit time is called rate of reaction and is expressed in units of
Integrated rate law for second order reactions:
Taking in the example of following reaction,
And the reaction follows second order rate law,
Then the relationship between the concentration of
The above expression is called as integrated rate for second order reactions.

Chapter 14 Solutions
Chemistry & Chemical Reactivity
- Consider the following statements: In general, the rate of a chemical reaction increases a bit at first because it takes a while for the reaction to get warmed up. After that, however, the rate of the reaction decreases because its rate is dependent on the concentrations of the reactants, and these are decreasing. Indicate everything that is correct in these statements, and indicate everything that is incorrect. Correct the incorrect statements and explain.arrow_forwardAccount for the relationship between the rate of a reaction and its activation energy.arrow_forwardExplain what is meant by the average rate of a reaction.arrow_forward
- Based on the diagram in Exercise 12.83, which of the reactions has the fastest rate? Which has the slowest rate?arrow_forwardRank the following in order of increasing reaction rate. (a) Dynamite exploding (b) Iron rusting (c) Paper burningarrow_forwardConsider the decomposition reaction 2X2Y+ZThe following graph shows the change in concentration with respect to time for the reaction. What does each of the curves labeled 1, 2, and 3 represent?arrow_forward
- How does an increase in temperature affect rate of reaction? Explain this effect in terms of the collision theory of the reaction rate.arrow_forwardOne of the concerns about the use of Freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the following reaction: CCl2F2(g)Freon-12hvCF2Cl(g)+Cl(g) Chlorine atoms can act as a catalyst for the destruction of ozone. The activation energy for the reaction Cl(g) + O3(g) ClO(g) + O2(g) Is 2.1 kJ/mol. Which is the more effective catalyst for the destruction of ozone, Cl or NO? (See Exercise 75.)arrow_forwardDefine these terms: (a) unimolecular reaction (b) bimolecular reaction (c) elementary reaction (d) overall reactionarrow_forward
- In Exercise 11.39, if the initial concentration of N2Oj is 0.100 .\1. how long will it take for the concentration to drop to 0.0100 times its original value? The decomposition of N2O5 in solution in carbon tetrachloride is a first-order reaction: 2N2O5—»4NO2 + O2 The rate constant at a given temperature is found to be 5.25 X 10-4 s-’. If the initial concentration of N2O5 is 0.200 M, what is its concentration after exactly 10 minutes have passed?arrow_forwardBased on the kinetic theory of matter, what would the action of a catalyst do to a reaction that is the reverse of some reaction that we say is catalyzed?arrow_forwardFor the decomposition of one mole of nitrosyl chloride, H = 38 kJ. NOCl(g)NO(g)+12Cl2(g) The activation energy for this reaction is 100 kJ. a Is this reaction exothermic or endothermic? b What is the activation energy for the reverse reaction? c If a catalyst were added to the reaction, how would this affect the activation energy?arrow_forward
