From the values of ΔH and ΔS predict which of the following reactions would be spontaneous at 25°C. Calculate the minimum temperature at which each reaction will become spontaneous. Enter "NONE" if the reaction is not spontaneous at any temperature. (a) ΔH = 12.4 kJ/mol, ΔS = 88 J/K · mol spontaneous at 25°Cnot spontaneous at 25°C K (b) ΔH = 8.7 kJ/mol, ΔS = -90.0 J/K · mol spontaneous at 25°Cnot spontaneous at 25°C K

A musician plays a concert A note on her violin ($f_A = 440 \text{ Hz}$) and finds that it is out of tune. The note is too low in frequency by 1 Hz. The length of the string is $L = 0.75 \text{ m}$ and the total mass of the string is $m = 0.05 \text{ kg}$. (a) What is the tension in the string? (b) Should she tighten or loosen the string to tune it? Explain.

For the circuit shown below: a. Write down a valid set of node voltage equations. b. Write the set of valid node voltage equations in matrix form. c. Solve for each node voltage value by hand, showing your steps (similar to lecture notes). You may use Cramer's rule and/or row reduction techniques in your steps. d. Based on your solutions from part c above, determine ix and vx. 2.2(k) Ω (50.8 Ω 2.5 mA 10 V 6508.5 Ω 4.7(k) Ω 2. For the circuit shown in problem 1 above: a. Use the results of part b from problem 1 above and write a MATLAB script to solve the matrix. In the first line of your script, include ECE201 Fall 2022 - then type your name on that same first line of your script. b. Attach a .pdf of your MATLAB script to this assignment. c. Print the results of MATLAB's solutions to this problem, showing all node voltage results, to a .pdf file and attach those results to this assignment.
