Worksheet: Phase Changes at Varying Temperatures
In this worksheet, we will practice explaining the effects of pressure and temperature on phase transitions and predicting the features of a phase diagram.
Consider the phase transformation process . The value of for this process at 1 bar pressure and a temperature of 298 K has a value of 2.900 kJ/mol, and the value of for the process under these same pressure and temperature conditions has a value of J/K⋅mol. If the temperature increased from 298 K to K, but the pressure remained constant at 1 bar, would the thermodynamic stability of graphite relative to diamond increase, decrease or stay the same?
