Problem 64

Which of the substances in each of the following sets would be expected to have the lowest melting point? Explain why. a. H2, N2, O2 b. Xe, NaCl, C (diamond) c. Cl2, Br2, I2

Step-by-Step Solution:
Step 1 of 3

Chem 1020 Spontaneity Spontaneous- A process (reaction or phase change) that takes place without continuous energy from an external source o Example- A ball rolling downhill Nonspontaneous- a process that requires continuous input of energy from an external source o Example- A ball rolling uphill Enthalpy is effected by two factors; enthalpy and entropy. This is shown in the equation for Gibbs free energy. ΔG=ΔH-TΔS  ΔH= Enthalpy T= Temperature ΔS=Entropy  Entropy- A measure of disorder or chaos or randomness o Entropy increases as:  Temperature increases  Pressure decreases
