URGENT Use the Maxwell-Boltzmann diagram to show how changes in temperature and addition of catalysts increase reaction rate"
As temperature increases the rate of reaction increases as the number of particle with activation energy increases
and as we add catalyst the activation energy of the reaction decreases and the rate of reaction increases

Use the Maxwell-Boltzmann distribution of speeds to show that <vx>=0.
Use the Maxwell-Boltzmann distribution of speeds to estimate the fraction of N2 molecules at 392 K that have speeds in the range 200. – 210. m·s−1. Hint: The fraction of molecules with speeds in the range v to (v + dv) is equal to f(v)dv, Please show entire integration for boltzmann formula.
The diagram below shows, for a given temperature T, a Boltzmann distribution of the kinetic energy of the molecules of a mixture of two gases that will react together, such as nitrogen and hydrogen. The activation energy for the reaction E-A, IS marked.
29 (6 pts) How do concentration of reactants, temperature and catalysts affect the rate of a chemical reaction? Explain. Concentration of reactants: mcreases more collisions within the reactants. collisions Temperature: Increase in temperature causes increase in more and more energy in collisions. (increases rate? Catalyst: Lowens energy of activation of reactants cate? (increases rutes
27. Use a labelled potential energy diagram to show how the addition of a catalyst would impact the activation energy of an endothermic reaction.
Explain the collision model and why concentration and temperature affect rate Explain how catalysts affect reaction rate. Draw and interpret reaction energy diagrams – catalyzed, uncatalyzed, and multi-step.
6. Use the diagram of the loanable funds model to show how an increase in taxes shifts the IS curve.
(10 points) Define relaxation modulus and draw how it changes with increasing temperature for a glassy polymer (15 points) Define relaxation time, and elaborate a reasoning to predict changes with temperature. 1. 2. (75 points) Derive the response of a Maxwell element in an engineering stress-strain test in which the rate of tensile strain is maintained constant. 3. Assume e 0 for t 0 and reasonable values for the constants: (a) Plot stress as a function of time. (b) Plot...
6. The following is the phase diagram of hexane. Show the changes in this diagram if you added toluene to this solvent. Particularly show the changes in the phase boundary between A and B, and between B and C. Pressure (atm) 10 20 30 40 50 60 Temperature (C) 70 80 90
28. Use a labelled diagram to show how the value of Q can be used to predict the direction a reaction with a known K value at constant temperature and pressure will proceed.
