🤓 Based on our data, we think this question is relevant for Professor Van Der Sluys' class at PSU.
Which of the following processes have a ΔS > 0?
a. 2NH3(g) + CO2(g) → NH2CONH2(aq) + H2O(l)
b. lithium fluoride forms from its elements
c. 2HF(g) → H2(g) + F2(l)
d. potassium iodide dissolves in pure water
We’re asked to determine which of the following processes have a ΔS > 0.
Also, recall that if:
• ΔS > 0 or ΔS = (+); entropy is increased
• ΔS < 0 or ΔS = (–); entropy is decreased
Remember that phase changes lead to a change in entropy:
Also, recall that:
