The universe’s obsession with mess — and how chemists put a number on it 🎯 Learning outcomes Candidates should be able to: Define the term entropy, S, as the number of possible arrangements of the particles and their energy in a given system. Predict and explain the sign of the entropy changes that occur: during…
🎯 Learning Outcomes Candidates should be able to: Define and use the term enthalpy change with reference to hydration, ΔHhyd, and solution, ΔHsol Construct and use an energy cycle involving the enthalpy change of solution, lattice energy, and enthalpy change of hydration Carry out calculations involving these energy cycles Explain, in qualitative terms, the effect…
