Question 1
Imagine a closed container holds 2 moles of gas A and 3 moles of gas B at 298 K. If the mixture decreases in temperature to 273 K without any changes in pressure or volume, discuss the expected change in entropy and why.
💡 Hint: Relate the effect of temperature on particle movement and arrangement.
Question 2
Given standard entropies for X = 200 J K⁻¹ mol⁻¹ and Y = 300 J K⁻¹ mol⁻¹, and the reaction X + Y → Z with standard entropy S°(Z) = 600 J K⁻¹ mol⁻¹. Calculate the entropy change for this reaction.
💡 Hint: Recall the entropy change formula and substitute correctly.
