Amount of N O x present after 5.25 hours should be determined. Concept Introduction: Order of a reaction: The order of each reactant is represented by the exponential term of the respective reactant present in the rate law and the overall order of the reaction is the sum of all the exponents of all reactants present in the chemical reaction . The order of the reaction is directly proportional to the concentration of the reactants. The integrated rate law for the first order is as follows: ln [ A ] = ln [ A 0 ] − k t where, [ A 0 ] = initial concentration k= rate constant t = t i m e [ A ] = c o n c e n t r a t i o n a f t e r t i m e t Half–life period: It is the time required for the reactant (substrate) concentration to reduce to the one-half of its initial concentration. The half–life period for first order reaction is as follows: t 1/2 = 0.693 k Where, k = Rate constant t 1/2 = half-life

An expression for the root mean square velocity, vrms, of a gas was derived. Using Maxwell’s velocity distribution, one can also calculate the mean velocity and the most probable velocity (mp) of a collection of molecules. The equations used for these two quantities are vmean=(8RT/πM)1/2 and vmp=(2RT/M)1/2 These values have a fixed relationship to each other.(a) Arrange these three quantities in order of increasing magnitude.(b) Show that the relative magnitudes are independent of the molar mass of the gas.(c) Use the smallest velocity as a reference for establishing the order of magnitude and determine the relationship between the larger and smaller values.
The reaction of solid dimethylhydrazine, (CH3)2N2H2, and liquefied dinitrogen tetroxide, N2O4, has been investigated for use as rocket fuel. The reaction produces the gases carbon dioxide (CO2), nitrogen (N2), and water vapor (H2O), which are ejected in the exhaust gases. In a controlled experiment, solid dimethylhydrazine was reacted with excess dinitrogen tetroxide, and the gases were collected in a closed balloon until a pressure of 2.50 atm and a temperature of 400.0 K were reached.(a) What are the partial pressures of CO2, N2, and H2O?(b) When the CO2 is removed by chemical reaction, what are the partial pressures of the remaining gases?
