20 mark for review quantity that would be zero for a pure, perfect crystal at 0 k a enthalpy of formation b entropy c gibbs free energy d lattice energy
Answer
Brief Explanations:
According to the third - law of thermodynamics, the entropy of a pure, perfect crystal at absolute zero (0 K) is zero. Entropy is a measure of the degree of disorder. At 0 K, the atoms in a perfect crystal are in a completely ordered state, so entropy is zero. Enthalpy of formation, Gibbs free energy, and lattice energy are not zero under these conditions.
Answer:
B. Entropy
