In the calorimetry experiment, what will happen if the temperature was recorded prior to the stabilization of the temperature reading? Select one: O a. Magnitude of calculated AH actual value

Application 14. Given the function f(x) = 3x3 - 48x find the following: (Round to 1 decimal place) a) The x and y intercepts [K/U: ] b) The local maximums and minimums [A:. c) Find any points of inflections [A: I d) Graph the function [C 5

Use the data on Table 1 to construct a linear y versus x graph of In(1/time) versus 1/temperature(K) in Excel. The graph should have a title that indicates it is a plot of data for the linear form of the Arrhenius equation. Each axis should have a named quantity label and x-axis should additionally have a unit label. Attach to this graph to the report page. 3. State the slope(with correct units and sign) of the line on the graph constructed in #2 4. Use the stated slope in #3 to determine the energy of activation in kilojoules per mol. Show your work. 5. Using the trendline equation for your graph, predict the time that the reaction…

Figure 1 shows the stress-number cycles to failure (S-N) curve for a cylindrical acetal polymer bar. The cylindrical bar is 200 mm long and 15 mm in diameter is subjected to a vibrational load at one end of the bar at a frequency of 500 vibrations per minute with a load of 50 N. 60 50 8 Stress amplitude (MPa) 30 20 10 105 106 107 108 Cycles to failure Figure 1: The S-N fatigue curve for an acetal polymer. 104 (i) Evaluate the duration (in hours) the part will survive before breaking? (ii) Suppose the cylindrical bar is to survive for one million cycles under conditions that provide for equal compressive and tensile stresses. Evaluate the maximum stress, the minimum stress, and the mean stress on the part during its use. Explain the effect of frequency on the stress application would have on your answers.
