(a)
Interpretation:
The nitrous oxide decomposition is whether zeroth, first or second order reaction has to be determined by plotting appropriate graphs. The value of rate constant of nitrous oxide decomposition reaction has to be determined.
Concept Introduction:
Order of a reaction: Order of a reaction is defined as the sum of exponents of the concentrations in the rate law of the given reaction.
The
For a reaction,
- If the plot drawn between concentration of reactant and time is linear, then it is a zeroth order reaction
- If the plot drawn between ln[reactant] and time is linear, then it is a first order reaction
- If the plot drawn between 1/[reactant] and time is linear, then it is a second order reaction
- For the zeroth and first order reaction, the graph has a negative slope whereas the graph has a positive slope for a second order reaction.
(b)
Interpretation:
The molarity of AB after
Concept introduction:
The rate law for a zero order reaction:
A zero order reaction is defined as the reaction whose rate which does not depend on the concentration the reactants.
(c)

- When boron trifluoride reacts with ammonia, the following reaction occurs: BF3(g)+NH3(g)BF3NH3(g)The following data are obtained at a particular temperature: (a) What is the order of the reaction with respect to BF3, NH3, and overall? (b) Write the rate expression for the reaction. (c) Calculate k for the reaction. (d) When [ BF3 ]=0.533M and NH3=0.300M, what is the rate of the reaction at the temperature of the experiment?arrow_forward. Account for the increase in reaction rate brought about by a catalyst.arrow_forwardAt 573 K, gaseous NO2(g) decomposes, forming NO(g) and O2(g). If a vessel containing NO2(g) has an initial concentration of 1.9 102 mol/L, how long will it take for 75% of the NO2(g) to decompose? The decomposition of NO2(g) is second-order in the reactant and the rate constant for this reaction, at 573 K, is 1.1 L/mol s.arrow_forward
- Give at least two physical properties that might be used to determine the rate of a reaction.arrow_forwardOne experimental procedure that can be used to determine the rate law of a reaction is the method of initial rates. What data are gathered in the method of initial rates, and how are these data manipulated to determine k and the orders of the species in the rate law? Are the units for k. the rate constant, the same for all rate laws? Explain. If a reaction is first order in A, what happens to the rate if [A] is tripled? If the initial rate for a reaction increases by a factor of 16 when [A] is quadrupled, what is the order of n? If a reaction is third order in A and [A] is doubled, what happens to the initial rate? If a reaction is zero order, what effect does [A] have on the initial rate of a reaction?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_forward
