A series of experiments were conducted where the equilibrium constant (K) was determined at various temperatures (T). The data was then graphed (shown below). The equation of the line is listed on the graph. Use the graph to determine AS (in J/mol·K). -30 0.0031 -30.30.003 0.0032 0.0033 0.0034 0.0035 0.0036 0.0037 -31 -31.5 y = -6861.2x - 9.2495 In (K) -32 -32.5 -33 -33.5 -34 -34.5 -35 1/T in K. Answer:

It is not practicable to measure the intercept directly at 1/T-0, so calculate In A from the measured slope and the coordinates of any point on the graph. Compare your values of E and A with those obtained by previous students, namely E-52 kJ mol 1 and A- ~10 dm mol-1 s1 For E-45.3953 kJ mole equation: y -5460.1 x + 10.272- At 273K, 301K...

A chemical reaction was conducted at varying temperatures so that the equilibrium constant, K was determined at each. Thereafter it was assumed that the reaction enthalpy, DeltarxnH° was independent of temperature and a graph of 1/T (in Kelvin) vs. ln K was plotted yielding a straight line with a slope of –1586.33. What was the resulting DeltarxnH° value and was it an exothermic reaction

A chemical reaction was conducted at several different temperatures (measured in K) and the equilibrium constant was measured at each one. Plotting the data on a graph with ln K on the y-axis and 1/T on the x-axis gives a linear plot with slope = -4594.6 and y-intercept = 13.6. What is ΔrH° (in kJ mol-1) and ΔrS° (in J mol-1 K-1)?

3.3) [8 pts] A sample of 29 randomly selected automobile owners were asked to keep a record of the kilometers they travel. The random sample showed an average of 28,350 kilometers and a standard deviation of 5,237 kilometers. Assuming the underlying population is normally distributed, test the hypothesis that automobiles are driven on average more than 28,000 kilometers per year at the 10% level.
