Consider the plot and draw the lines as shown: -10- In Nv:N 0.0010 0.0015 0.0020 0.0025 0.0030 0.0035 1/T Hence, from the pl

Find out the activation energy by using the following relation: Here, activation energy is Qv, Boltzmann constant is k = 8.62

Number of potential defect sites: N-NAP N =- g 100 cm3 6.023x1023 atoms -*8.4 molcm3 1 m3 63.5 g mol = 8.0x1028 atoms/m

Hence, the number of vacancies at 800°C is: No = Nexplete No = 8.0x102% xexpl Ny = 2.237x1024 atom/m 0.96975 | 8.62x10--(800+

will work with up to 3 partners (similar to a lab group) to prepare a written report which analyzes kinetic data that has been provided to you. All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...
