[ 2 + 2 + 2 + 3 + 3 = 12 marks ] Question 5 (a) Briefly explain why we cannot find simultaneous eigenfunctions of Lt, L, and Lz. An electron in a hydrogen atom is in the n = 2 state. Ignoring spin, write down the list of possible quantum numbers {n, l, m} (b) For two qubits briefly explain, giving examples, the difference between a product state and an entangled state (c) Consider a system of identical...

Find the standard entropy of the universe for the following reaction at 298K. CH4(g) + 2 O2(g)----> CO2(g) + 2 H2O (g) Is the reaction spontaneous? Explain.
(a) Find the change in entropy when 2 kg of Oxygen at 600C are mixed with 6 kg of Nitrogen at 400C in a rigid vessel. The initial pressure of each component is 103 kPa and remains the same for that of the mixture. (b) What is the amount of heat transferred during the mixing process? Given, Cv = 0.743 J/g.oK for Nitrogen and Cv = 0.659 J/g.oK for Oxygen.
Please explain Entropy Changes Associated with State Changes. Below you will find key questions. 1. Know and understand how entropy relates to a phase change. 2 Know how to predict the sign of entropy change. 3 Calculate the entropy change for a change of state.

Part 2: Entropy is a focus of Topic 10. Entropy is given the symbol 'S'. The more mixed up things are, the higher the entropy. The more ways for a thing to be considered the same (how many ways can 3 pennies have 1 head and two tails), the higher the entropy. Entropy and disorder are closely related. As disorder increases, entropy increases. For example, consider your sock drawer. If all the socks are paired, the entropy is relatively low,...
