Question

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, but if the socks are all mixed up, the entropy is much higher. If there are many ways to arrange the particles in the system, then there is greater disorder. Systems with greater disorder have greater entropy. Let's try and solve some problems.(3 points) 1. Consider the following reactions. Use your intuition to complete the table below Reaction Does disorder increase or decrease? Does entropy increase or decrease? What is the sign of AS? 2H2O(g) + O2(g) → 2H202(1) CO2(3) C02(g) K*(aq) + Cl(aq) →KCI(s)
